alleryWhen a pure TALL pea plant (TT) is crossed with a pure DWARF pea plant (tt), the F1 generation will all be:
ATall, because T is dominant over t
BDwarf, because t is dominant over T
CHalf tall and half dwarf, by 50:50 ratio
DMedium height, exactly between tall and dwarf
Answer & Solution
Correct answer: A. Tall, because T is dominant over t
The F1 generation is all Tt (heterozygous).
Since T is DOMINANT over t, all F1 plants are TALL.
The recessive trait is masked but reappears in F2 in a 1:3 ratio (dwarf:tall).
