A.
1/4
AnswerB.
1/2
C.
1/9
D.
1/16
Answer: Option A
Solution
Answer: Option A
Solution:
When a Tall plant (Tt) in a pea is crossed with another Tall plant (Tt), the probability of obtaining a dwarf plant is 1/4.When Tt × Tt, the ratio of progeny formed will be 1 Homozygous tall (TT), 2 heterozygous tall (Tt), and 1 homozygous dwarf (tt).
Therefore, the probability of dwarf plants will be 1/4.
