Mendel's Pea Experiment: What Will the Result Be?

What would be the result of a cross between two round, yellow peas with genotypes Rr,Yy?

A) round, blue B) round, yellow C) wrinkled, green D) wrinkled, yellow

Answer:

According to Mendel, a cross between two round, yellow peas (both with the genotype Rr,Yy) would result in mostly round, yellow peas.

Gregor Mendel, known as the father of modern genetics, conducted experiments with pea plants to understand how traits are inherited. One of his experiments involved crossing two pea plants with the genotypes Rr, Yy. In this case, "Rr" represents the round seed shape and "Yy" represents the yellow seed color.

When Mendel crossed two pea plants with the genotype Rr,Yy, the offspring would inherit one allele for round seeds (R) and one allele for yellow seeds (Y) from each parent. Since the dominant traits for seed shape are round (R) and for seed color are yellow (Y), the resulting peas would be mostly round and yellow.

Therefore, the most likely outcome of a cross between two round, yellow peas with genotypes Rr,Yy would be mostly round, yellow peas as they can only pass on the alleles for round and yellow traits to their offspring.
