adjective Biology .
1.
having dissimilar pairs of genes for any hereditary characteristic.
Going by my high school biology about the blue-eyed thing. I have brown eyes, my dad has brown eyes my mom has hazel. Now here's where things get tricky... My Dad's father, has Hazel eyes my mom's father had Hazel eyes, and my Mom's mom has Blue.
So both my parents have recessive blue eye genes, meaning I have them too. Theoretically, if I married a man with blue eyes (yes please God) my baby could have blue eyes, (if I could have kids)...
So I'm thinking that what
Dis was saying the only way for a woman to have a baby with blue eyes is if she had the recessive blue eye gene and her husband had blue eyes. If she doesn't have the gene, then it doesn't matter if hubby has blue eyes, the baby will have the recessive gene.
Of course it's been 11 years since high school bio and I could have completely screwed this up.
