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

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?

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

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!!

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

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

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

Do a punnet square

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

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..........

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.

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

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

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...

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)
