In a hypothetical embryo, a high concentration of a morphogen called morpho is needed to activate gene P; gene Q is active at or above medium concentrations of morpho; and gene R is expressed so long as any quantity of morpho is present. A different morphogen, called phogen, activates gene S and inactivates gene Q when at medium to high concentrations. If morpho is produced in the anterior end of the embryo and phogen is produced in the posterior end of this embryo, which genes will be expressed in the middle region of the embryo

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
