Question

If a plant that has wrinkled seeds has a parent with round seeds, what is the plant’s genotype? (Assume round is dominant over wrinkled)A. RRB. RrC. rrD. ww

Answer 1

Knowing that round seeds (R_) is a dominant trait over wrinkled seeds (rr), and the offspring is a plant with the recessive trait (rr), we can conclude that the parent must be a heterozygous for the trait (Rr) while the plant genotype is a homozygous recessive (rr). Therefore the plant genotype (wrinkled seeds offspring) is ww (c).
