Hatshy [7]

Answer:

Answer:

The correct answer would be 0.589

The Hardy-Weinberg equation is p + q = 1

In addition, the frequencies of p and q in a Hardy-Weinberg population remain the same generations over generations.

So, the value of q =  ⇒ 0.411

Thus, the value of p = 1 - 0.411 ⇒ 0.589.

So, the expected value of p would be 0.589
