Can anyone determine the probability of my son having one hair/eye color over another?

Question

I have blue eyes dark blond hair. my mother has dark brown hair and brown eyes, my father has dark blond curly hair and blue eyes, my sister has blue eyes and light brown curly hair. my husband has dark brown hair and eyes. his mother has blond curly hair and blue eyes his father has dark brown curly hair and brown eyes his brother has dark brown curly hair and brown eyes. Can any biology buffs out there give me an idea of what the likelyhood of my son having a certain hair/eye color?

I understand that no one can tell me 100% but I know that a rough estimate can be given. I did a test online for eye color. I just now want to know hair color.

If i remembered how to do a punnet square, I would do one.

Answer 1

Going by the info you gave there's a 33.33% chance for the hair color to be either blond, brown, or light brown, but the probability of it being curly is about 75%.
Now eye color has a 50% chance of being either brown or blue.
Hope this helps some and remember there are no guarantees when it comes to genetics.
Good Luck!!

Answer 2

All I can say for sure is that your son has 50% chance of having blue /brown eyes. You have blue eyes, so you are homozygous recessive (ee). Your husband has brown eyes but his mother has blue eyes, so he must be heterozygous (Ee). If you do a punett square, you get 50:50 for eye color.

Hair color is determined by multiple genes, so it can't be done with simple monohybrid punett square.

Curlyness, I thought was a one gene trait. I think it might be an example of incomplete dominance where homeozygous dominant is curley, heterozygous is wavey, and homozygous recessive is straight... but I'm not really sure, so I'm not going to get into it...

Answer 3

if a woman whose father was color-blind had a male child, that child would have a 50% chance of being color blind. If she had a female child there would be a 50% chance that the child would be a carrier for color-blindness. All girls whose fathers are colorblind will at least carry the gene for colorblindness. In order for a girl to actually be red-green colorblind, she must have a mother who is a carrier AND a father who is colorblind so it should be D

Answer 4

1.consider brown(B_) as being dominant over blond (bb)
2.your mother will be Bb, father bb, sister Bb and you bb
3your husband will be Bb, his brother Bb,his father BB/Bb, his mother bb
4. so you bb + Bb from your husband = 1/2 bb and 1/2 Bb
5.So genetically the chance of having either blond or brown is 50%.
-hair colour is of multifactorial iheritance so enviromental and nutritoinal factor play a role (small role)

Answer 5

Its about 50/50 on getting a blue eyed child, but hazel and green can pop up anytime - no matter if a parent has them or not.

Answer 6

more than likely he will have darker hair and eyes. I have blue eyes/red hair, my husband has black hair/brown eyes. My doc. told me if we had 4 kids only one would have blue eyes..........

Answer 7

there are more factors to hair/eye color than the ones we know

Answer 8

Do a punnet square

Answer 9

Usually the darker colors are passed down. I'm not sure exactly why.
