In four o’clock plants, there are three phenotypes for flower color but only two alleles. In one population, q2 = 0.169, and the
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.

The value of q⁸ is given as 0.169

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
