In snapdragons, red flower color (R) is incompleletely dominant over white flower color (r); the heterozygotes producepink flowers. A red snapdragon is crossed with a white snapdragon,and the F1 are intercrossed to produce the F2.
(a) Give the genotypes and phenotypes of the F1 and F2, alongwith their expected proportions.
(b) If the F1 are backcrossed to the white parent, what willthe genotypes and phenotypes of the offspring be?
(c) If the F1 are backcrossed to the red parent, what will thegenotypes and phenotypes of the offspring be?
the reversion precisely reversed the original change that produced the typ- mutant allele.
