Green-grey eyes and dark blond hair? (genes)?

ok , this is about genes. my husband has green-grey eyes and dark blond hair, while i have brown and black hair colour. what will be our daughters eye and hair colours?

Well - darker eye and hair colour tends to be dominant over lighter colours, so the odds are your daughter would have dark hair and brown eyes (though babies are almost all born with "baby blue" eyes, and the colour develops over time).



However - hair and eye colour are complex traits; they are controlled by more than one gene/allele. Also, either of you could be a "carrier" (ie - recessive heterozygous) for a trait you do not disply yourself.



It might make more difference if you also advised of your parents' hair and eye colours.

It all depends on who has the more dominant gene.
