Consider a trait or phenotypic feature or even a recessivedisorder with decidedly non-random geographic patterning to thefrequency of the trait, feature, or allele where it is highfrequency in some populations and low frequency in otherpopulations (non-random frequency distribution). What are themechanisms or ways that you could testable hypotheses to explainhow that pattern developed and why it is maintained – i.e. forcesof evolution? Population histories? Cultural mechanisms?Developmental adaptation? Acclimatization? Describe and illustratewith one of the disease alleles or phenotypes presented in thetextbook and lecture or if there is one of particular interest toyou that we didn’t discuss, use that one! (Hint: Discuss all themechanisms and factors that we consider when developingevolutionary explanations for traits, phenotypes, and alleles. Notewhether there is always one mechanism? Or, are there multipleforces or mechanisms?)
