Answer:
C. YyRr
Explanation:
The cross was done between pure-bred Yellow Wrinkled and Green Round plants. The genotype of the pure breeding yellow wrinkled parent plant: YYrr. The genotype of the pure breeding green round parent plant: yyRR.
A cross between YYrr and yyRR would obtain the progeny in the following ratios:
YYrr x yyRR= All YyRr (yellow and round)
Plants often go into the dormant state to protect themselves from suboptimal conditions (usually harsh winters). A tough outer covering can protect the plant from freezing, the buds are covered for this same reason. The leaves fall to minimize the loss of energy since in the winter there is usually not enough sunlight to sustain the process of photosynthesis.
