  Unit 11 7F Lets remember An allele is an alternative form of one gene B stands for black b stands for brown The allele would be Genetic Drift An evolutionary mechanism in which allele frequencies change in a population. adaptationist. . explanations. …. 5) A feature may be a by-product of selection for another trait. Spandrel = a phenotypic characteristic that is a byproduct of the evolution of some other character, rather than a direct product of adaptive selection. . 23.1 – Mutation & sexual reproduction produce genetic variation that makes evolution possible. 1) Microevolution. Change in the allele frequencies of a population over generations. Evolution on the smallest scale. Random change in allele frequencies from 1 generation to . the next.. Individuals who survive . & pass on their genes are not necessarily the “fittest” . Leads to a loss of genetic variation. . Chapter. 12-1. Pan-. gaea. . “. all. - earth. ” .

Many genes have at least two forms alleles.. All organisms have genetic variation that is “invisible” because it involves small differences in biochemical processes..
