Question

In a certain plant species, the allele for wrinkled seeds (W) is dominant to the allele for smooth seeds. What is the phenotype result of a cross between a true-breeding wrinkle-seeded group of plants and a true-breeding smooth-seeded group of plants?

A.
all smooth seeds, no wrinkled seeds

B.
1/4 wrinkled seeds, 3/4 smooth seeds

C.
all wrinkled seeds, no smooth seeds

D.
1/4 smooth seeds, 3/4 wrinkled seeds

Answer 3

so a true breeding wrinkle-seeded group of plants can only produce wrinkled seeds, that means that it contains the dominant allele only, because if it didn't than sometimes it would also produce smooth seeds sometimes

Answer 4

so that would mean my answer would be C. all wrinkled seeds, no smooth seeds

Answer 5

likewise the genotype of the smooth-seeded group will only contain the recessive allele since it can only produce the smooth seed
