3. In guinea pigs, the p locus has alleles for red or black eyes and the q locus has alleles for fur or hairlessness. A hairless male guinea pig with red eyes is mated with a furry female guinea pig with black eyes who is heterozygous for both loci, PpQq. The alleles in this heterozygous parent are in the repulsion configuration. The recombination frequency between the two loci, p and q, was determined to be 28%. If the testcross produces 400 offspring, predict the number of each phenotype among the progeny.
