On chromosome 3 of corn there is a dominant gene (A1), which together with the dominant gene (A2) on chromosome 9, produces colored aleurone. All other genetic combinations produce colorless aleurone. Two pure colorless strains are crossed to produce an all colored F1. a) what were the genotypes of the parental strains and the F1?

b) what phenotypic proportions are expected among F2?

c) what genotypic ratio exists among the white F2?

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
