Practice questions testing deep understanding of Darwinian selection, Hardy-Weinberg, and speciation.
Q1. During the Industrial Revolution in England, the population of peppered moths dramatically shifted from mostly light-colored moths to mostly dark-colored (melanic) moths. Explain how Darwin's theory of Natural Selection accounts for this shift.
Q2. Assertion (A): According to the Hardy-Weinberg principle, allele frequencies in a population will remain constant from generation to generation only if there is absolutely no mutation, no migration, and mating is completely random. Reason (R): Mutations and non-random mating introduce new alleles or preferentially select certain alleles, actively driving evolution and upsetting the genetic equilibrium.
