Evolutionary Analysis ch 7 question and answers graded A+ 2023 already passedMigration - correct answer the movement of alleles between populations homogenize - correct answer High levels of migration ________ populations. Migration has a larger impact of this on small populations than large populations. sampling error - correct answer In a small population, chance events produce outcomes that differ from theoretical expectations. This kind of random discrepancy between the theoretical and actual results is called_____ genetic drift - correct answer sampling error in the production of zygotes from a gene pool founder effect - correct answer When populations are small that have been started by a group of individuals that have been moved to a new location, the allele frequecies in the new population are likely, simply by chance, to be different from their frequencies in the source population. Ex. Island hopping Silvereyes of Australia and Pinglelap atoll survivors faster - correct answer small populations drift away from heterozygosity ____ than larger populations initial frequency - correct answer Sewall Wright proved that the probability that any given allele in a population will be the one that drifts to fixation is equal to the allele's _____ heterozygosity - correct answer the frequency of heterozygotes in a population substitution - correct answer When genetic drift is the only mechanism at work, the rate of ______ is equal to the mutation rate neutral theory - correct answer this theory says advantageous mutations are exceedingly rare and most alleles of most genes are selectively neutral. In most populations the rate of evolution will indeed be equal to the mutation rate
