When two heterozygotes mate, the dominant trait will appear in

When two heterozygotes mate, the dominant trait will appear in both the F1 and F2 generations. The dominant trait masks the recessive trait in the heterozygous individuals of the F1 generation. However, in the F2 generation, there is a 3:1 phenotypic ratio of dominant to recessive traits, as some of the F1 individuals may carry the recessive trait and pass it on to their offspring. Thus, the dominant trait will continue to appear in subsequent generations as long as it is present in the gene pool.
