Question

Quizplus · Accepted Answer

If two organisms are true-breeding for a certain genetic characteristic, they must be homozygous for that trait. When these organisms are mated, their offspring will be heterozygous for that trait, and therefore not true-breeding themselves. As a result, the offspring will be either 100 percent homozygous for the dominant allele or 100 percent heterozygous, depending on the mode of inheritance. The P generation represents the parental generation, so the offspring would represent the F1 generation. The gametes produced by the offspring will carry one allele for each gene, not two.
