Question

Why did only about one fourth of mendel's f2 plants exhibit the recessive trait

Answer 1

Only one fourth of them had a recessive trait because the plant would have needed to get the trait from both parents for it to appear in the plant. It would have been a 50/50 chance if both parents are heterozygous, therefore, if both parents give the gene it would be a 25% chance.
