Question

What percentage of the pea plant offspring are expressing the recessive trait yellow?

Answer 1

Answer:100%

Explanation:Since the Y (yellow) allele is dominant over the G (green) allele for pea plants, 100% of the YG offspring will have a yellow phenotype, as Mendel observed in his breeding experiments.

Answer 2

If both parents are heterozygous for the trait, then 25% of the offspring will be homozygous recessive (yy) and exhibit the recessive trait (yellow).
