Question: Is it likely that a male with blue eyes and a female with brown eyes have a child with blue eyes?
I heard that blue eyes are a recessive gene, and that brown eyes are a dominant gene. If we were to have kids, how likely would the child have blue eyes?

Answers:

Well, lets draw out a punnet square and see, okay? So you're correct, brown is dominant and blue is recessive. Lets use the letter 'E' for eyes. E is brown, and e is blue, okay?
E E
e Ee Ee
e Ee Ee

As you can see the dominant trait masks the blue eyes, BUT this is assuming the female with brown eyes is a homozygous dominant. Maybe she is heterozygous dominant, lets check a square on that too.
E e
e Ee ee
e Ee ee

In this situation blue eyes have a 50% chance due to the fact in a heterozygous situation, brown is dominant. Homozygous recessive is blue eyes which has a 50% chance. Since you don't know which she is (unless you did a family tree trait test or something) then you can't accurately say your chances. The tables are leaned towards brown eyes.

I hope this helps!



No, but there is a chance. If the female's mother had blue eyes, its 50%
2 blue eyed people having a kid with brown eyes, no chance



There's a 20% chance that the baby will have blue eyes



brown is more dominant than blue but it could happen to be that the child will have blue eyes



hes going to come out with blue eyes unless she cheats on you
