4. assume that one allele is complete dominant over the other for the following questions.
a. two individuals heterozygous for a single trait have children. what is the expected phenotypic ratio of the possible offspring?
b. two individuals heterozygous for two traits have children. what would be the expected phenotypic ratio of the possible offspring?
c. crossing two individuals heterozygous for two traits results in the same phenotypic ratio as for a single trait. are the genes for these two traits on separate chromosomes or on the same chromosome? explain your answer. (remember that the gene for each trait is located at a locus, a physical region on the chromosome.)
