2. The genotype of F1 individuals in a tetrahybrid cross is TtXxYYZz. Assuming independent assortment of these four genes, what are the probabilities that F2 offspring will have the following genotypes? a) ttXXTTZZ b) TtxxYYZZ c) ttxxYYzz d) ttxxyyzz

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
