okay.. i read the bottom half of your response and i dont think you understand that genes are already set as either recessive or dominant. In real life, okay this is real life now: a brown eye pigment gene is dominant over nearly every other eye pigment gene. And a blue eye would be recessive. So it would be:
B = brown eye dominant gene
b= blue eye recessive gene
So a guy with brown eyes can either be homogenous for brown eyes (BB) or heterogenous (Bb) to have the brown eye gene dominate over the blue eye gene. And a girl with blue eyes can only be homogenous for blue eyes (bb) or else the dominant gene (B) will dominate over the blue gene. And that is how dominant over recessive genes work.
Go slow pal, that's too much for some.
But I have a question. Does gayness run in the family?
I will be back eventually with some evidence and will ask your knowledgeable opinion about that...
