Question

When Mendel crossed a true-breeding purple-flowered pea plant with a true-breeding white-flowered pea plant, the probability of the genotype (Pp) to appear in the offspring is, what is the ratio

Answer 1

Genotype of one true-breeding parent is PP. The other true-breeding parent has genotype pp. So, all offspring will be heterozygous. The probability for Pp is 100%, there will be no ratio.
