Question

What genotypic ratio is expected in a cross between two heterozygous parents (Pp x Pp)?00003 purple: 1 white2 purple: 2 white1:2:11:3

Answer 1

In a cross between parents heterozygous in a monohybrid cross, the ratio of the offspring will be:

3:1 for phenotypic trait, and for genotypic 1:2:1 (PP-Pp-Pp-pp) using the Punnett Square. Being two heterozygous, one homozygous recessive, and one homozygous dominant and two observed phenotypes.
