Mendel studied pea plants dihybrid for seed shape (round versus wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele (r) and
the yellow allele (Y) is dominant to the green allele (y).
The table below shows the F1 progeny that result from selfing four different parent pea plants.
Use the phenotypes of the F1 progeny to deduce the genotype and phenotype of each parent plant.



Answer :

Mendel researched round versus wrinkled seeds in pea plants and seed color (yellow versus green). Just to refresh your memory, the round allele (R) is dominant to the wrinkled allele (r), and the yellow allele (Y) is dominant to the green allele (y).

What are the genotypes of the pea plants that produce green and yellow seeds, respectively?

Thus, the genotype of a heterozygous yellow-seeded plant will be "Yy," whereas a green-seeded plant will have the genotype "yy" (as the recessive allele is expressed only in homozygous conditions).

What is the genotype of the parent of the yellow round?

As a result, genotype YYRR stands for the pure-breeding round yellow parent, while genotype YYRR stands for the pure-breeding green wrinkled parent. Character-specific gene pairs assort independently of one another during gamete development.
