NOTE: Please follow the instruction about to answer the following questions. I need a medium length paragraph answer for each question. Please make sure it answers the question specifically.
Q1 : Why are there higher frequencies of the sickle cell allele where malaria is present?
Q2 :How did human farming influence the evolution of the sickle cell allele in human populations?
Q3 : Looking to the future, what factors (environmental, genetic, or social) could cause alteration in frequencies of the sickle cell in human populations? What changes to the sickle-cell allele do you envision as most likely, and why?
