In corn, the trait for a tall plant (T) is dominant to the trait for a dwarf plant (t) and the trait for coloured kernels (C) is dominant to the trait for white kernels (c). In a particular cross of corns, probability of white kernels is 0.25 and the probability of a kernel being coloured is 0.75. Which of the following most probably represents the parental genotypes?

Question

In corn, the trait for a tall plant (T) is dominant to the trait for a dwarf plant (t) and the trait for coloured kernels (C) is dominant to the trait for white kernels (c). In a particular cross of corns, probability of white kernels is 0.25 and the probability of a kernel being coloured is 0.75. Which of the following most probably represents the parental genotypes?, TtCc × TtCc, TtCc × ttCc, TtCc × ttcc, TTCc × ttCc

MARKS App · Accepted Answer

Out of 8 plants, 6 plants have coloured kernals 2 plants have coloured / white kernal. So the genotype of plants will be TtCc and ttCc.
