What color hair and eyes will my children have?

I have very dark brown hair, yet it can be told apart from black, and I have hazel eyes, brown next to the pupil and green all around the brown. My mother has brown hair/brown eyes. My father has my hair color and eye color, however, his mother had blonde hair. If I marry someone with blonde hair and blue eyes, what color hair/eyes will our children have? What are the possibilities out of blonde, light brown, medium brown, dark brown hair? and blue, green, hazel, or brown eyes?

you need to learn the punnet square method and you'll have it then



What color hair and eyes will my children have?

Your baby will have genes from both yours and the father's side. He/she will have characteristics determined by which gene is dominant. So nothing can really be said.



What color hair and eyes will my children have?

You should do a Punnett Square. But, you have to identify which traits are dominant and whether you are a carrier of a recessive gene. Brown eyes, for instance, are a dominant trait, but your dad passed it on to you. The chances of having a blond baby are slim because you might not carry that recessive gene for blond hair and your brown hair is dominant. As for you colored eyes, your baby might have blue, hazel, or brown eyes. For that one you have to wait until you have the kid in your arms.



What color hair and eyes will my children have?

Eye and Hair color are polygenic traits. There are atleast 3 genes that determine eye color. Hazel eye color is overall somewhat heterozygous among those genes... if you had children w/ someone w/ very pale blue eyes, that's completely homozygous recessive, whereas blue eyes would carry 1 dominant allele and the other 5 would be recessive... therefore, chances are more likely that your children will have hazel, green, or blue eyes-- However, there is a slight likelihood that brown eyes (probably only brown or light brown) could occur.



Hair color is also determined by at least 3 genes-- so if you have medium brown and she's very blonde (completely recessive) then you probably won't have children w/ darker hair; however, it is possible b/c so many genes play a factor in this physical appearance (phenotype).



To figure out the color, you would have to do several punnett squares for each one.
