In the context of Hardy-Weinberg, what does a 'recessive' trait imply?

• It requires two copies of the allele to be expressed

• It cannot be calculated

• It is less common in the population

• It is always deleterious

If 16% of a population is unable to taste a certain chemical due to a recessive allele, what is the frequency of the recessive allele (q)?

• 0.8

• 0.4

• 0.6

• 0.16

In a population, if the frequency of the dominant allele (p) is 0.6, what is the frequency of the recessive allele (q)?

• 0.7

• 0.4

• 0.6

• 0.3
