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 in 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

If there are 400 red flowers, 200 pink flowers, and 100 white flowers. Solve for the frequency of the dominant allele.

• 0.76

• 0.86

• 0.57

• 0.71
