I'm scared to enter such a contentious thread, but... The OP'er said, "the male does not give any specific traits that the female doesnt" This is not really true. Sidestepping the subject of genes that may or may not be sex specific, there's an important evolutionary parameter of sex in general that should be considered by serious breeders. That is; Nature tends to take more chances with, or 'throw the dice' with males than females, be they plants or humans. Remember the bell curve? Beethovens over here, Mansons over there. I'm certainly not against feminizing or selfing, but I do realize that variation is needed for selective pressure to result in improvement. Males provide wider variation than females.
