The answer to this question depends on the particular genetic factor or combination of genetic factors that are responsible for the trait of red or blonde hair. Generally speaking, brown hair is the most dominant hair color, followed by black, and then red or blonde.
In situations where two versions of the same gene occur, the recessive trait (the one that is not dominant) does not “win” over the dominant trait. For example, if both parents carry genes for red and blonde hair, the child could potentially inherit either hair color.
In some cases, however, if a person has two copies of a particular allele (gene version) they may express the recessive trait more prominently. This is known as the homozygous recessive model and is particularly true when both copies of the gene come from the same parent.
In summary, it is hard to say which of these hair colors is more “dominant” as it depends on the particular genetic factors being expressed.

Which parent determines red hair?
At the most basic level, the parent who contributes the most recessive trait to the gene pool determines red hair. This is because red hair is a recessive trait, meaning that it is only expressed when both parents pass the same gene for red hair to the child.
Because this trait is recessive, both parents need to be carrying the gene for red hair in order for it to be passed on to the child. Therefore, the parent who contributes the most recessive trait to their offspring will determine whether the child has red hair or not.
The color of a person’s hair is determined by a unique combination of several genes, and each gene determines the amount of pigment (or color) present in each strand of hair. Red hair is a recessive trait, meaning that it requires two copies of a particular gene (inherited from both parents) in order for the pigment to be expressed.
So, while both parents contribute to the hair color of their child, the parent who contributes the most recessive gene—the one who carries two copies of the recessive red hair gene—will determine whether the child has red hair or not.
Does red hair come from Mom or Dad?
The color of a person’s hair is determined by their genetic background and is a combination of the gene variants passed down from both the mother and father. Each parent passes down a combination of gene variants (alleles) from each one of their parents, and when it comes to hair color, each parent has two alleles to pass down (one from the mother’s side and one from the father’s side).
The combination of alleles that each parent passes down to their child can result in the child having red hair. So, to answer your question, red hair can come from either the mother or the father, depending on their own genetic makeup and the combination of alleles they pass down to their child.
Can two brown haired parents have a redheaded child?
Yes, two brown haired parents can have a redheaded child. This phenomenon is determined by a trait called polygenic inheritance. This is when a trait is determined by multiple genes, like hair color.
Hair color involves more than one gene and can have different versions. This means even if two brown haired parents both have the same brown hair color gene, but one of them has the gene for red hair, it is possible that the red-haired gene could be passed on to their child and they could have a redhead.
Additionally, red hair is a recessive trait and it is possible that both parents could be carriers of the recessive red hair gene, but not express it themselves. Therefore, these two parents, who both don’t have red hair, could pass on two copies of the red hair gene to their child.
What color eyes do most redheads have?
Most redheads have light colored eyes, with either blue, green, or hazel being the most common. Some people with red hair have eyes of a darker amber or brown hue, but this is typically seen in people with auburn or darker red hair.
Eye color is quite varied among redheads, so you’re likely to come across redheads with eyes of different hues. Eye color can also be affected by environmental factors, such as exposure to sunlight, which may cause eye color to become darker over time.
What hair colour gene is strongest?
The exact answer to this question depends on a number of factors, including genetic background, individual genes, and the environment. Generally speaking, however, the gene for dark hair is thought to be the strongest, being the most dominant of the various hair color genes.
Dark hair is often expressed in people of mixed parentage, and has also been found to be dominant in many genetic studies. Additionally, dark hair is the predominant hair color in parts of the world where there is an unequal balance of blonde vs.
brunette hair. Dark hair is considered the dominant gene because it is the most common color among humans and is often the original choice in cases of alleles that vary in shade.
What color hair will my baby have if both parents have brown hair?
The color of the baby’s hair will depend on the genetic makeup of both parents. While the chances of the baby having brown hair are very high, the exact color of their hair will depend on the genetic makeup of both parents.
Genes can sometimes interact and express themselves differently in different generations, so the final color of the baby’s hair is impossible to predict. If both parents have brown hair, there is a higher chance the baby will also have brown hair than any other color, but there are still chances the baby’s hair could come out light brown, dark brown, auburn, or any other shade in between.
What hair Colours make a ginger baby?
A ginger baby can typically have a variety of hair colors, including strawberry blonde, light brown, dark blond, and auburn. The exact color of the hair will depend on a variety of factors, such as the hair color of the parents, the individual genetic makeup of the baby, and environmental factors.
Ginger babies may have redder hair as they become older depending on the hair color of their parents. In some cases, the baby’s hair may lighten over time, depending on the hereditary characteristics.
Can a brunette have a ginger baby?
Yes, it is possible for a brunette to have a ginger baby. This is because different shades of hair color are determined by a person’s genes and can be passed down from generation to generation. Different hair colors can be expressed in different family members due to the genetic variability of making an individual.
So, it is possible for two brunette parents to produce a red-haired baby. In genetic terms, this happens when both the mother and father carries a gene variation for red hair, even though neither of them may have red hair themselves.
Is red hair dominant over brown?
No, red hair is not dominant over brown. Brown is actually the most common hair color in the world, with around 90% of the human population having some shade of brown hair. Red hair is much less common, presenting itself in only about 2% of the population.
Red hair is caused by a variety of genetic combinations, and as such can not be said to be dominant over any other hair color.
What genes are inherited from father only?
The genes that are only inherited from the father are known as “paternal genes. ” These genes are passed down from father to child through the Y chromosome, which women do not carry. Examples of paternal genes include those that determine a child’s physical appearance, such as eye color, hair color, and certain facial features.
Other examples of paternal genes are those that determine a child’s susceptibility to certain genetic diseases, such as hemophilia and Duchenne muscular dystrophy.
Paternal genes can be identified in the laboratory by a process known as “genetic fingerprinting. ” This method involves comparing the DNA of the father with that of the child to determine if the same paternal genes are present.
Studies have shown that the percentages of shared genes vary from one father-child pair to another, but it is generally accepted that fathers provide approximately 40% of the genes passed on to their children.
Which characteristics always inherited from father?
Fathers tend to pass on many genetic and non-genetic characteristics to their children. The most common inherited traits can be both physical and behavioral.
One of the most obvious inherited physical traits from a father to a child are certain facial features, including things such as eye color, hair color, and dimples. Interestingly, the tallest parent tends to pass on the greatest height to their children.
Fathers with deep voices may pass on the same trait to their children. Additionally, fathers tend to pass on their blood type and immune system to their children.
Non-physical traits are also inherited from fathers and often have more of an impact on their children’s lives than physical traits. Intelligence, ambition, and athleticism are examples of personality traits that can be passed on from a father.
Research suggests that fathers also tend to pass on their coping skills, problem-solving abilities, sense of humor, and even their politeness to their children. Additionally, a father’s strong work ethic and ambition are often passed down to their children or grandchildren.
Finally, fathers pass on their values and beliefs to their children, both verbalized and nonverbalized. How a father acts and interacts with their world will influence how a child will approach their environment.
Fathers also influence their child’s development of religion, ideas about education and career, and relationships.
Which chromosome is only passed by the father?
The Y-chromosome is the only chromosome passed exclusively from father to son. The Y chromosome is the shortest chromosome, containing only 78 genes, and is responsible for male sex determination and other aspects of male characteristics.
Sons receive their father’s Y chromosome and mothers pass their X chromosome to both sons and daughters, resulting in males having one X and one Y chromosome (XY) and females having two X chromosomes (XX).
Who passes more genes mom or dad?
It is impossible to definitively answer the question of who passes more genes, either mom or dad, because it varies depending on each individual situation. On a general level, we know that mothers always pass on mitochondrial DNA, while fathers pass on both nuclear DNA and mitochondrial DNA.
Nuclear DNA holds the majority of our genetic information, including the genetic material related to physical characteristics. However, both the mother and father pass on nuclear DNA, with the mother contributing one full chromosome set and the father contributing a second set.
Therefore, both parents contribute an equal number of genes to the offspring’s genetic makeup.
But, in some special cases, for example, if the father contributes a mutated gene or if the mother is a carrier of a genetic disease, there may be a slightly different pattern of gene contribution from each parent.
There are theoretical models of autosomal dominance, reciprocal genetics, and other mechanisms that could also play into the contribution of each parent’s genes.
Overall, the answer to this question depends upon individual family genetics and the specific genes in question. While it is impossible to definitively say that one parent passes more genes than the other, we can generally assume that both parents contribute an equal number of genes to the offspring’s genetic makeup.
Can a child have red hair if parents don t?
Yes, it is possible for a child to have red hair, even if neither of their parents have red hair. This is because in humans, hair color is determined by a combination of genetics and chemical processes, and the combination of genes that a child inherits from their parents doesn’t always have to match the hair color of their parents.
Each parent will pass an equivalent of half of their genetic makeup to their child, and the combination of those genes – plus other factors such as the environment and hormonal activity – will determine the child’s hair color.
For example, if both parents carry the gene for red hair but the gene is recessive in each of them, so neither parent has red hair, their child is still likely to inherit the gene for red hair and have red hair as a result.
