I have a report on mutation related diseases and I will be writing about Sickle Cell Anemia because it is interesting. You see, people have this notion that mutation is bad and I want to change that. I want to show the good side of mutation, in this case malaria resistance. I want to add more. Can you give me other mutation related stuff that is beneficial?

Can a recessive trait become dominant?

I've always wondered what role a grandparent plays in the traits of his or her grandchildren. For example, I have blonde hair and blue eyes; my mother and father have brown hair and hazel eyes and black hair and blue eyes, respectively. What kind of effect would this have on my children? If, say, my wife was also blonde and blue-eyed, would it somehow lessen the chances of our children being blonde and blue-eyed?

If people with Rh- in their extended family keep marrying into strong Rh bloodlines, is it possible to wipe out the Rh- out of a bloodline completely? So much so that eventually the Rh- won't be able to recur in their offspring?

Why is it that some alleles are dominant, and some are recessive!? I have been looking EVERYWHERE and all I find is what, not WHY. Why is an allele dominant or recessive?

Does the dominant allele for a given trait show up as the prevalent phenotype in the population at large? For example, the presence of dimples is controlled by a dominant allele, but the majority of people do not have dimples. Why is this?
