Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced b
all had the dominant trait. The Punnett square showed that there was a 50 percent chance of the offsp
genes. So, the student assumes that he made an error in determining the genetic makeup of the plants
student made an error, or is there another explanation? Explain your answer.

Round seed is a dominant trait ( depicted by dominant R allele) whereas wrinkled seed is a recessive trait ( depicted by recessive allele r).

According to the law of segregation of genes, the alleles will separate from one another during gamete formation.

Pea plant with round seeds will produce two gametes that is R and R whereas plant with wrinkled seeds will produce r and r gametes.

When the parents are crossed, they will result in the offspring with genotype Rr ( that will exhibit round seed phenotype).
