Suppose you have monohybrid pea plants in your garden and find that they produce round seeds to wrinkled seeds in the ratio of 3:1. If the alleles are designated R and r, respectively, what are the probable genotypes of the wrinkled seeds produced by your plants?
A.RR & Rr
B.RR only
C.RR & rr Rr
D. only rr only

Respuesta :

rr only because you know that R (Round) is the dominant allele and to get a wrinkled pea you will have to have rr (a monozygotic recessive plant) 

Answer:

Rr only
