In generation 1, the recessive allele has a frequency of 0.6 and in generation 40, the recessive phenotype has a frequency of 0.36. Is the population is Hardy-Weinberg?

• No, the frequency changed from one generation to another.

• Yes, the frequency changed from one generation to another

• No, the frequency remained the same from one generation to another

• Yes, the frequency remained the same from one generation to another
