In peas, yellow seed color (y) is dominant to green seed color (y). a homozygous green pea plant is crossed with a heterozygous yellow pea plant. what is the predicted phenotypic ratio of the offspring?

a) 50 percent yellow, 50 percent green
b) 50 percent yy, 50 percent yy
c) 100 percent yellow, 0 percent green
d) 100 percent yy, 0 percent yy

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
