Tall pea plants are dominant over short pea plants. If a heterozygous tall pea plant(Tt) is crossed with a short pea plant(tt), what percentage of the offspring will be homozygous dominant?

Respuesta :

Answer: The percentage of the offspring that will be homozygous dominant is zero.

Explanation: Since tall pea plants are dominant to short pea plants, a cross between a heterozygous tall pea plant (Tt) and a homozygous short pea plant (tt) will produce four offsprings: two heterozygous tall pea plants (Tt) and two homozygous short pea plants (tt). Tt x tt = Tt, Tt, tt, and tt.

Tt is heterozygous dominant for tall height while tt is homozygous recessive for short height.
