Me and my partner both have brown eyes…
My side of the family have all brown eyes so I’m assuming we don’t have the blue eye gene.
My partners parents: his dads side have all brown eyes but his mother and aunts and grandfather have blue eyes. So my husband must be a carrier.
Will my brown eyed genes dominate his blue eye genes or is it possible for a blue eyed baby?
It’s so interesting how it works
In: Biology
The default color of the eyes is blue. However most people have the gene that makes the brown pigments so the eyes turn brown. This does mean that if you have two copies of the gene for brown eyes then all your kids will have this gene and will get brown eyes. There are however two assumptions which could be wrong here. Firstly it is very hard to figure out if you you have two versions of the gene or only one just by looking at the color of the eyes of your family. It is possible that many of them also only have one copy of the gene and you would never know. So there is a possability for you to birth kids with blue eyes for this reason. Another assumption is that the gene for brown eyes actually activates in your kids. It is possible for some genes to not activate or only partially activate, especially in kids. And if they do not produce enough brown eye pigments then their eye color will be blue or possibly a shade between blue and brown, green. This is more common in people with only one copy of the brown gene.
