Sure. : ) I was assuming that the sorting of genetic traits would be random,
so the probabiltiy of having much in the way of aril genes would be small,
but that it could happen. Are you saying the aril genes have a higher
probability of being dropped or that there is some active selective process
in the sorting of heterozygous chromosomes that makes aril genes be dropped
preferentially?
