Question

Consider Mendel’s experiments involving the trait of round versus wrinkled peas. In some experiments, Mendel removed the anthers of the flowers from a plant that was true-breeding for round peas and applied pollen from the anthers of a plant that was true-breeding for wrinkled peas. What would have happened if Mendel missed some anthers that he was trying to remove from the true-breeding round pea plants, and then counted the peas produced by a plant that bore a mix of round and wrinkled pollen?

Explanation / Answer

all the anthers of true breeding plants for round peas (RR) were supposed to be removed. pollen of wrinkled pea (rr) plant were supposed to be applied to round pea plant. this would result in RR x rr hybridization, which would give Rr peas that are round (since round phenotype is dominant)

let us suppose he forgot to remove some anthers. these anthers (RR) would hybridize with RR gametes of the same plant, which produces RR peas that are round.

therefore, the result would be same in F1 generation. however, he would not get the ratio of 1:2:1 in F2 generation.
