39 genetic drift worksheet answers

Genetic Drift; When one trait becomes more common in a population due to random chance (not because it is advantageous or non-advantageous) Population Bottleneck: is event in which a large number of a species is killed causing the remaining population to reproduce. This causes all of the offspring to have similar traits as

Genetic drift is the change of allelic frequencies in the gene pool due to random sampling. This simulation will explore how sample size can influence the effect on genetic drift on the gene pool. -Note: The two types of genetic drift, population bottlenecks, and the founder effect are not suggested vocabulary words in the HSSCE companion document.

Genetic drift, however, happens completely by chance. A factor which may disrupt equilibrium is the occurrence of selection for a specific trait in the population. If one trait is favored by the environment, then it will alter the gene pool as this will impact the potential for reproduction and thus the frequency of the alleles which shall lead ...
