Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. a pansy that is homozygous for purple
flowers (pp) is crossed with a pansy that is homozygous for pink flowers (pp).

which genotypes will be included for the offspring in the punnett square for this cross?
a) pp, pp, and pp
b) pp and pp
c) pp and pp
d) pp only

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
