To have blond hair do both of your genes have to be for blond hair?

not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene


What are the genetic factors that determine the inheritance of red hair color?

The inheritance of red hair color is determined by a specific gene called MC1R. This gene controls the production of a pigment called pheomelanin, which gives hair its red color. Variations in the MC1R gene can result in different shades of red hair, and inheriting two copies of the gene from both parents is necessary to have red hair.


The gene for red hair is recessive to the gene for black hair. What will be the hair colour of a child if he inherits a gene for red colour from his mother and a gene for black hair from his father Ex?

The child will have black hair because the gene for black hair is dominant over the gene for red hair. Since the child inherits one gene for red hair from the mother (recessive) and one gene for black hair from the father (dominant), the dominant black hair gene will express itself. Therefore, the child's hair color will be black.


What determines how tall you grow and whether your hair is curly or straight?

What are the chances of inheriting a recessive gene for hair color?

The chances of inheriting a recessive gene for hair color depend on the genetic makeup of your parents. If both parents carry the recessive gene, there is a 25 chance of inheriting it. If only one parent carries the gene, the chances are lower.


What hair color is most common?

Brown because it is a dominant gene


What does the outward expression of a gene mean?

Genes can produce visible body types, for example, hair color, eye color, height, skin color, and various other things. Most genes do not have such an easily observable result, but if there is any observable result at all, even one that you would have to observe with a microscope, then that is the outward expression of that gene.


One human trait that is determined by multiple alleles?

Human Height. It is also influenced by nutrition.


Does the red hair color have to be in the father side for the child to have red hair if the mothers side has that hair gene color?

You've basically answered your own question here. No, the red hair gene needn't be on the fathers side, since the mother already has it. The chances become greater if dad has that gene for the child to have red hair, but if the mothers side has the gene, then there is a 1/4 chance it will have red. If dad has it, then more than likely the child will have red hair.
