WebThe Punnett square calculator is an online tool that allows you to setup traits of the parents to predict frequency of occurence of particular genotype and phenotype in progenies. To use Punnett square please follow link below. Monohybrid, Autosomal Monohybrid, Sex-linked Dihybrid, Autosomal Dihybrid, Sex-linked Blood types WebOut of these crosses, all of the F1 offspring had the phenotype of one parent, and the F2 offspring had a 3:1 phenotypic ratio. On the basis of these results, Mendel postulated that each parent in the monohybrid cross contributed one of two paired unit factors to each offspring, and every possible combination of unit factors was equally likely. coupons for slimming world
