olydactyly is an autosomal dominant trait that results in the presence of additional digits on the hands and feet. The incidence in Caucasians is approximately 1 in every 1300 births while in Africans and African Americans, the prevalence is 1 in every ~150 births. Fortunately, this trait does not cause any deleterious effects on one's health. Actually, there are a number of individuals who have been successful football players that were born with polydactyly. In 1902, a study found that the allele frequency of the recessive allele (p) was 30% in the local population. Last year, a follow-up study was published which assessed the genotypes of the same local population. The following data were obtained: pp = 10%; Pp = 40%; PP = 50% Use the above information to answer the questions below. Use the word bank for a subquestion when provided. What is the frequency of p (recessive allele) in the follow-up study? Round your answer to the nearest tenth. Did the population evolve? (word bank: yes, no) Briefly provide a scientific explanation as to why the population did/did not evolve.
