I know only God can predict this, and different things happen to different human beings. I am just curious on what is the more dominant gene, what would be more likely for my child to look like. I am more Irish and have dirty blonde hair and blue eyes (my hair got darker but is still a light brown). My boyfriend is Italian and has dark brown hair--looks black unless in sun--and he has brown eyes. What do you think wouldbe more of the dominant gene if we had a child?
