1.) In corn, Zea mays, mutant genes for anther ear (an) and fine stripe (f) are carried at linked loci separated by approximately 20 map units. These mutant genes are recessive to their counterpart alleles, an+ and f+, which control the wild-type expressions of these traits. The gene for colorless aleurone (c) is recessive to its dominant allele for colored aleurone (C) and is found on a chromosome different from that carrying the an and f loci. If you selfed a phenotypically wild type corn plant with the following genotype: an+ f /an f+, Cc What percentage of the progeny would have anther ear, fine stripe and colored aleurone?

2.) What percentage of the progeny would have anther ear, fine stripe and colorless aleurone if the wild type parent that was selfed had the genotype: an+ f+ / an f; Cc ?
