An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant. What is the probability that a seed from the cross will produce a tall plant?

Respuesta :

Answer:

50% (0.5)

Explanation:

homozygous shortness = tt

heterozygous  F1 plant = Tt

crossing them will yield

tt            Tt

Tt ( tall seed)  tt ( short seed)   Tt  (tall seed)  tt (short seed)

the ratio is 1 to 1

the probability for tall seed = 1/2 × 100 = 50%
