Two scientists are cutting samples of leaves for analysis. one scientist always clips a sample from the base of the leaf near the stem, and the other scientist always clips a sample from the tip of the leaf. this illustrates a procedural error. calibration error. measurement error. unit error.

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
