A type of flower called the Rhododendron has a CW allele that leads to red flower color and a CW allele that leads to white flower color. Rhododendrons with the heterozygous genotype CWCW have flowers with red and white patches. Another gene controls leaf shape, with the dominant allele R leading to oval leaves and the recessive allele r leading to rounded, shorter leaves. If you cross two Rhododendrons that are heterozygous for flower color and leaf shape: a) What ratio/fraction of offspring would you expect to have red flowers and oval leaves? b) What ratio/fraction of offspring would you expect to have white flowers and rounded leaves? c) What ratio/fraction of offspring would you expect to have red-and-white flowers and oval leaves?
