A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?) homozygous recessive, rr heterozygous, Rr homozygous dominant, RR In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?) Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR. Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr. Perform a test cross with a plant that has wrinkled peas—if any offspring give wrinkled peas, then the new plant’s genotype is Rr.

Question
A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?)
homozygous recessive, rr
heterozygous, Rr
homozygous dominant, RR
In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?)
Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR.
Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr.
Perform a test cross with a plant that has wrinkled peas—if any offspring give wrinkled peas, then the new plant’s genotype is Rr.
Expert Solution
Step 1
homozygous dominant trait =round peas (RR)
homozygous recessive trait=wrinkled peas (rr)
Heterozygous trait = round peas (Rr)
