Solution

The phenotypic frequency of a trait in a population is calculated by dividing the number of individuals displaying the trait by the total number of individuals in the population.

In this case, the trait is being a black cat.

Step 1: Identify the number of individuals displaying the trait. Here, 72 cats are black.

Step 2: Identify the total number of individuals in the population. Here, there are 100 cats in total.

Step 3: Divide the number of individuals with the trait (72) by the total number of individuals (100).

72 ÷ 100 = 0.72

So, the phenotypic frequency of black cats in this population is 0.72.

Therefore, the correct answer to the multiple choice question is 0.72.
