A selective sweep refers to what? A: The replacement of pre-existing genetic variation by the variation surrounding a selected allele B: Natural selection that targets a particular--"selected"--allele C: An advanced cognitive capability observed in expanded human social networks D: Patterns of phenotypic variation associated with assortive mating

What information is provided by the Hardy-Weinberg calculations? A: it tells if there has been a change in the allele frequency of a population B: it tells if there has been changes to the phenotypes observed in a population C: it tells if an individual is fit for survival D: it tells if an individual is likely to undergo evolution
