Eye Color Calculator

Really cool (even though I already knew how to do this on my own, I still thought it was fun)

That's weird. It says I won't have any brown-eyed children, even though I have brown eyes.

Okay, I did it again and now all my kids have brown eyes. I'm so confused.

In real life, I have brown eyes, my husband has blue, son #1 has brown eyes, and son #2 has blue.

There's no option for hazel eyes, and that's what hubby has.

And he doesn't know what color his parents' eyes are.

My husband's eyes are hazel too, between blue and green, I just put blue.

AmyRoo it depends on what your parents have. Brown is a dominant gene and so if you have one child with blue eyes (and he is at least one year of age, because before that eye color continues to establish) that means you carry one dominant brown gene and one recessive blue. Your husband has blue eyes so he carries two recessive genes. He will give one of those to your offspring. You will give either a brown or a blue/green gene. It also depends on your parents. This can get complicated but I love this stuff.

My parents both have brown eyes, and I have brown eyes, but since I have a green and a blue eyed sisters I know that both my dad and my mom carry recessive genes. There is a 66% chance that I am carrying a recessive gene and thus a 33% chance my children could have blue/green eyes because my husband has two recessive genes. Am I confusing everyone? I love this genotype stuff

Ha, I called hubby's mom to ask her and FIL's eye colors, and the calculator says it's not possible for their eyes to be those colors.

Of course that's probably because we were putting green for FIL's greenish-hazel, and brown for hubby's brownish-hazel. Since MIL has blue eyes, that doesn't work.

I have green eyes, DH has blue, our child is 70% likely to have green eyes. Both of his parents have blue eyes, my mum has green my Dad has brown.

You didn't confuse me, I liked this in school too.

Our kids have a 50% chance of getting my color (which is kind of an olive green), 50% chance of blue. Natalie's are bright blue like my husband's. He was happy about that.

I think this stuff is interesting. I wish hair color was as easy to figure out.

50% chance of brown (i have brown eyes), 29% green (my dad has green) and 21% blue (dh is blue)

my kids have a 100% chance of having blue eyes

That calculator is pretty cool, but it doesn't work for an unexpressed recessive gene. My husband and I both carry the recessive gene for blue eye-color. We know this because our oldest son has blue eyes.

Both of his parents and all of his 8 siblings have brown eyes (and yes, I am 100% positive that the child is his ) Based on phenotypes alone... that site predicts that we shouldn't be able to have a blue-eyed kid, when in actuality we have a one-in-four chance.

I think it does work for unexpressed recessive genes, I have an un-expresed green eyed gene and it calculated the odds of having a green eyed child, I think in your case FM, the program must be assuming your in-laws are homozygous for the brown eyed gene, if that were true then your husband would also be homozygous and the chance of you having a blue-eyed child would be nil.

You are correct.

My husband's sister and her husband both have blue eyes too... so all their children will be blue eyed.
