WebGene frequencies are not changed for the species as a whole, but they change locally whenever different populations have different allele frequencies. In general, the greater … WebThe cross between the true-breeding P plants produces F 1 heterozygotes that can be self-fertilized. The self-cross of the F 1 generation can be analyzed with a Punnett square to predict the genotypes of the F 2 generation. Given an inheritance pattern of dominant–recessive, the genotypic and phenotypic ratios can then be determined.
