Question

A plant with the dominant trait, wrinkled seeds, is crossed with a plant that has non-wrinkled seeds. All of the offspring are all wrinkled-seeded. What is the likelihood that the gametes of the wrinkled-seeded parent plant contain one non-wrinkled allele? A) 0% B) 25% C) 50% D) 100%

Answer 1

The answer is D.  In order for the parent plant with dominant wrinkled seeds to produce any offspring with recessive round seeds, it must be heterozygous, meaning it has one wrinkled allele and one non-wrinkled allele in its genotype.

Answer 2

The correct answer is A.) 0%
