When a pure strain of tall plants (T/T) ...

When a pure strain of tall plants (T/T) with round peas (R/R) is crossed with a pure strain of short plants(t/t) with wrinkled peas (r/r), a `F_(1)` -generationis produced. The alleles for short and wrinkled are recessive to those for tall and round, respectively. When these `F_(1)` plants self-pollinate, what proportion of the `F_(1)` plants self -pollinate, what proportion of the `F_(2)`-generation is short with wrinkled peas?

A

Zero

B

1/16

C

1/2

D

9/16
