On chromosome 3 of corn, there is a dominant geneA1 which together with dominant gene A2 on chromosome 9 produces aleurone. All other genetic combinations produced colourless aleurone. Two pure colourless strains are crossed to produce an all coloured F1. (a) what were the genotypes of the parental strain and F1?
(b) what phenotypic proportions are expected among the F2?
(c) What genotypic ratio exists among the white F2?​

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
