Okay from what I have heard I do not believe that bananas are a sexlinked trait. It would be like colorblindness in humans except opposite. Basically it would be like a recessive trait in males with male bananas only being produced from the breeding of male banana to female banana. With females only needing one copy of the mutated gene to be a banana. This theory is blown out of the water since males have been produced from females bred to mutations other than banana.

Also I am doing a research project on the effects of incubation temps on balls. One incubator is at 86 degrees the other 91 degrees. I am getting 43% males at 86F and 54% males at 91F. So unless they are incubating at some crazy temp I can't see it being temp either. I just think it was "bad" odds for the past few years in the case of bananas. From what I have heard there have been quite a few banana males produced this year.
