Question

Pea plants are tall if they have the genotype TT or Tt, and they are short if they have genotype tt. A tall plant is mated with a short plant.

Which outcome below would indicate that the tall parent plant was heterozygous?

a. The ratio of tall offspring to short offspring is 1:1.
b. The ratio of tall offspring to short offspring is 1:2.
c. The ratio of tall offspring to short offspring is 2:1.
d. none of the above

Answer 1

The answer is 1:1.

Step-by-step explanation:

If you were to make a punnet square with the tall traits (Tt) and the short traits (tt) you would end up with two heterozygous dominant traits and two homozygous recessive traits. if you were to make a ratio I believe it would be 1:1
