Answer:

Tall offsprings: 13/25

Short offsprings: 12/25

Explanation:

According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:

13 tall pea offsprings

12 short pea offsprings

This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.

That is;

Tall offsprings: 13/25

Short offsprings: 12/25

In percentage, this can be represented as:

Tall offsprings: 13/25 × 100 = 52%

Short offsprings: 12/25 × 100 = 48%
