The answer is one in four plants had two alleles for the recessive trait. In the F1 generation of Mendel cross, all of the offspring will be heterozygous. After two heterozygotes cross, in the F2 generation, one in 4 plants will have two alleles for the recessive trait, one in 4 plants two alleles for the dominant trait, and 2 in 4 plants will be heterozygotes.
