Behavioral geneticists are primarily interested in a. studying the interaction between genes and environment. b. natural selection and the evolution of genes. c. discovering how genes control behaviors. d. proving that genes have the strongest influence on behavior.

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
