Answer:
D. Heterozygous: Rr
Explanation:
Smooth pea plants can have RR or Rr genotype. It is given that one of the pea plants has recessive rr genotype (wrinkled).
If it is crossed with a heterozygous pea plant (Rr) :
Rr X rr :
R r
r Rr rr
r Rr rr
As evident, half of the offspring will have smooth peas (Rr) and other half will have wrinkled peas (rr). Hence, genotype of unknown plant is Rr.
