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
Eye color is influenced by multiple genes but there’s one main gene causing brown eyes. The brown eyes gene has dominant alleles which means that you only need to inherit it from one of your parents to have brown eyes. You can still inherit the recessive “non-brown” allele from your other parent but it won’t affect your eye color.
If two parents have one dominant brown eye allele and one recessive non-brown eye allele, their child can inherit only the non-brown eye alleles and since there’s no dominant allele present, the child won’t have brown eyes.
