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?
