Explanation:
Detailed explanation-1: -So, the ratio between true breeding tall to true breeding dwarf is 1:1.
Detailed explanation-2: -A cross between a tall plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because tallness is the dominant trait. Thus, tallness is the dominant trait.
Detailed explanation-3: -Final Answer: If a pure tall plant is crossed with a dwarf plant, the offspring will be all tall.
Detailed explanation-4: -In the first of Mendel’s experiments, a tall purebred pea plant (TT) was crossed with a short purebred pea plant (tt). The result of this cross was all tall hybrid pea plants (Tt).
