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%
The answer is D. Â 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.
