The chromosome pictured below are from a fruit fly that is heterozygous for two traits. how many kinds of gametes could form if this were male? a female? explain how crossing over could affect the gametes that result.

I) I think four gametes are possible in either  a male or a female. That is; GY, gY, Gy, and gy.This is because both traits are heterozygous which means for a certain gene there are two different alleles. While in the case of homozygous there would only be one type of gametes since for a given gene there are two similar alleles.                                                                                                                                                                                                                                                                                                  ii) I think crossing over or recombination could cause the alleles that are linked with the wing color and the eye color genes to be exchanged between the two chromosomes in a pair, thus, resulting to new combinations of alleles. The final result would then be an increase in possible genetic variation. 

I’m going to go with b!

My pigs teeth have already came in years ago, with my first molars, and my second molars are pretty much in. my wisdom teeth will be unable to come in, but i'm getting those out on monday.
