For Mendel's experiment that crossed plants bearing green pods with those bearing yellow pods, describe the genotypic and phenotypic states of each generation (P, F1, and F2).
In the P generation, the parent with the green pods was genotypically homozygous dominant having two alleles for green pods while the parent with yellow pods was genotypically homozygous recessive having two alleles for yellow pods. In the F1 generation, all the individuals were genotypically heterozygous, having one allele for green pods and one allele for yellow pods, and all displayed the phenotype of the dominant allele. In the F2 generation, the genotypes were in a ratio of 1:2:1: there was one homozygous dominant individual, having two alleles for green pods, to every two heterozygous individuals, having one allele each for green and yellow pods, to every one homozygous recessive individual, having two alleles for yellow pods. The F2 generation phenotypes were in a ratio of 3:1: there were three plants with green pods, reflecting the total number of plants with at least one copy of the dominant allele, to every one plant with yellow pods.
