Very few genes have been located on the Y chromosomes of humans. Y-linked genes include a gene called testis-specific protein Y. A male with this gene will  

In cocker spaniels, black color (B) is dominant over red (b), and solid color (S) is dominant over spotted (s). If the genes are unlinked, and the offspring of BBss and bbss individuals are mated with each other, what fraction of the F2 generation will be black and spotted?  

Two individuals of genotypes AAbb and aaBB, respectively, mate with one another and produce an F1 offspring. If the two loci (A and B) are very closely linked, what will be the genotypes of most of the gametes produced by the F1 individual? (hint: think about what the chromosomes look like in the parents and F1).

A man with straight hair and a woman with curly hair get together and have quadruplets!  All of them have wavy hair.  What does this tell you about the nature of the hair type alleles?
