Q1. In peaches, homozygous condition GoGo produces oval glands at the base of the leaves, the heterozygous genotype GoGa produces round glands, and the homozygous condition GaGa results in an absence of glands. At another locus, a dominant allele S produces fuzzy peach skin and its recessive allele s produces smooth (nectarine) skin. An oval gland nectarine is crossed to a homozygous variety having fuzzy skin lacking glands at the base of its leaves. What genotypic and phenotypic proportions are expected in F2?

Q2. Six platyfish with dissimilar tail spotting patterns live in eastern Mexico. Five of them can interbreed and produce fertile offspring. One of them cannot interbreed with the other five. What can you conclude about these platyfish?
