Topic 7.11: Variations in Populations
Learning Objective: 7.11.A
Explain how the genetic diversity of a species or population affects its ability to withstand environmental pressures.
Essential Knowledge: 7.11.A.1
The level of variation in a population affects population dynamics. i. The ability of a population to respond to changes in the environment is influenced by genetic diversity. Species and populations with little genetic diversity are at risk of decline or extinction. ii. Genetically diverse populations are more resilient to environmental perturbation because they are more likely to contain individuals that can withstand the environmental pressure. iii. Alleles that are adaptive in one environmental condition may be deleterious in another because of different selective pressures. Illustrative examples: California condors; Black-footed ferrets; Prairie chickens; Potato blight; Corn rust; Genetic diversity and selective pressures; Antibiotic resistance in bacteria (not all individuals in a diverse population are susceptible to a disease outbreak).
