WebAS - The AS genotype means that an individual has one healthy allele (A) and one sickle-cell allele (S).Although two sickle-cell alleles would mean that a person has sickle-cell anemia and is at risk of death, one sickle-cell allele allows a person to be resistant to malarial infection while only having minor complications from the presence of the S allele. WebAug 21, 2000 · Answers: The first thing you'll need to do is obtain p and q. So, since white is recessive (i.e. bb), and 40% of the butterflies are white, then bb = q 2 = 0.4. To determine q, which is the frequency of the recessive allele in the population, simply take the square root of q 2 which works out to be 0.632 (i.e. 0.632 x 0.632 = 0.4). So, q = 0.63.
