Spread the love. Determine the genotypes (letters) of the parents. Bb x Bb. Set up the punnet square with one parent on each side. Fill out the Punnet square middle. Analyze the number of offspring of each type. Table of Contents show.Video transcript. - We're told that in a population of pea plants, some plants have round seeds and others have wrinkled seeds. The gene for seed shape in this population has two possible alleles. Remember, alleles are just versions of the gene. One allele or one version is for round seeds, which we're denoting capital R, and the other allele ...In the diagram, Punnett designated the gametes made in the male and female parents with single letters. The diagram shows that when the gametes combine, the offspring (inside the squares) again have the genes in pairs in their cells. Accounting for the random union of gametes is accomplished with the four squares in the diagram.

Dihybrid Cross Examples. Mendel took a pair of contradicting traits together for crossing, for example colour and the shape of seeds at a time. He picked the wrinkled-green seed and round-yellow seed and crossed them. He obtained only round-yellow seeds in the F1 generation.From this Punnett square, we can see that the possible genotypic ratios of their offspring are: 25% BB (brown body) 50% Bb (brown body) 25% bb (black body) The possible phenotypic ratios of their offspring are: 75% brown body. 25% black body.
