Help me the fuck out bros cause I haven't done shit for uni and I need to do a test and I have no clue how to do the questions below.

1. If the frequency of a recessive allele = 0.37
What does; p,q,q2,p2, 2pq equal?

2. 16% percent of a population express a recessive trait, what are the values of; p, q, q2, p2, 2pq? (round to two decimal places)
