is there any explanation for, like, if our parents both have blue eyes and you have black eyes?

Answer 1

It would be more likely for two brown-eyed parents to have a blue-eyed child, since the gene for dark eye color is dominant.

A person with dark eyes could have a gene for light eyes, but it's unlikely for a person with light eyes to have a gene each for dark and light eyes, because then s/he should have dark eyes.

Answer 2

The Punnett Square. Here's how it works...


Four boxes with either a capital P or a lowercase p. Example:
P|p
p|P
Upper Left Box: Dominant parent gene
Lower left box: Other parent gene
Upper Right Box: Dominant Physical Gene
Lower right box: Dominant Personal gene

Lets say P is dad, and p is mom. What the Punnett Square above is saying is that this person looks like their dad and acts like their mother. Sometimes (this is frequent with identical twins. I would know, I am one.) in the fight for control between your dad's gene and your mom's gene, they wipe that trait out, resulting in you developing your own trait. So if the gene that controls your eye color is different from your parents, that means that you did not get that from your parents. That was all you. Get It?

Answer 3

I'm sure you mean dark brown. It is sort of odd since blue eyes are not dominant and should not produce brown eyed children. Odd as it sounds, it’s much more common for brown-eyed parents to have blue-eyed children than for blue-eyed parents to have brown-eyed children.

That’s because brown eyes are dominant, and the eye color likely will have already shown up in a parent if the trait is in the gene pool. So absent the dominant brown-eyed gene, blue-eyed parents are likely to just keep on producing blue-eyed children.

However, blue-eyed parents can have brown-eyed children, although genetic processes for that possibility aren’t that well understood.

Answer 4

One inherits one's traits from one's grandparents, so if one of the four grandparents have black eyes, there is a 25% chance that the child will also have black eyes. If two of the four grandparents have black eyes, then the chance goes up to 50%.

For more details, look up Mendelian inheritance.

Answer 5

Someone in your family must have had black eyes. Thats the only explanation unless somethings wrong with you.

Answer 6

Sure, I have blue eyes and both my parents have them brown...I got the eyes color from my grandma's genes, like my aunts and a niece of mine, born a few months ago, with both parents having brown eyes!

Answer 7

black eyes in your case was a recessive. Two recessives make up a dominant. Blue/black....Blue/black. Two Blues yield Blue eyes. Two Blacks yield Black eyes.

Answer 8

both your parents cary genes from hundreds of thousands of generations so when an egg is fertalized half of the genetic make up from each parent is contributed to the structure of the ofspring. a latent gene is one that rarely shows up and thats what might have given you your black eyes.

Answer 9

DNA, somethimes things skip a generation or two. I've never Heard of black eyes, Brown, but not black.

Answer 10

. In general, 2 blue eyed people cannot produce a brown eyed child (grandparents being irrelevant) because blue eyes is recessive
