Gregor Mendel followed patterns of inheritance in pea plants, allowing him to elucidate the rules of inheritance, which we can now attribute ...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 ... Above is an example of a Punnett Square for an individual with brown eyes (heterozygous) and an individual who has brown eyes (homozygous).

It shows the alleles of the parents and the gametes in a tabular format. Learn how to use Punnett squares to predict the outcomes of Mendel's experiments and common traits such as seed color, blood type and eye color. There are three possible genotypes that result in different coat colors: Notice that if the animal inherits the homozygous recessive genotype of the "E" gene, "ee", then it will be yellow regardless of whether it is dominant or recessive for the "B" gene. So the recessive genotype of "ee" masks the phenotypic expression of the "B" gene.We can complete a Punnett square to find the possible offspring genotypes. Cross: bb x BB. If we complete the cross, we find that the possible offspring can only be Bb. …We need to complete the cells of the Punnett square by taking one allele from the column head and one from the row head for each cell.

Below is a Punnett square related to a hairline showing whether a person is going to have a straight hairline or a widow's peak. A widow's peak is a dominant trait; if a person has at least one dominant allele (W), they will have the widow's peak. The mom in this example is homozygous dominant for widow's peak. Our trihybrid cross example: RrYyCc x RrYyCc is a trihybrid cross. The shape of the pea is controlled by one set of alleles, where round is completely dominant to wrinkled: RR = round. Rr = round. rr = wrinkled. The second set of alleles in this example controls the color of the peas. Green is dominant to yellow: = green.Worked example: Punnett squares. Mendel and his peas.
