Population Structure: Genes & Phenotypes

These flashcards cover key concepts related to population genetics, safety in laboratory settings, and principles of evolutionary biology discussed in the lecture.

Lab Safety

Wearing lab coats and covering legs and feet is required for working with chemicals and equipment in labs.

Gene Flow

The movement of alleles from one population to another.

Genetic Drift

Stochastic changes in allele frequency due to random variation in fecundity and mortality.

Population Bottleneck

A sharp reduction in population size, causing a loss of genetic diversity.

Founder Events

Colonization by a few individuals that start a new population with limited diversity.

Stochastic Processes

Unpredictable evolutionary forces such as mutation and genetic drift.

Phenotypic Plasticity

The ability of a genotype to modify its phenotype in response to environmental changes.

Reciprocal Transplant Studies

Experimental method to test local adaptation by growing the same genotype in different environments.

Isolation by Distance

Accumulation of genetic variation due to geographically limited dispersal.

Local Adaptation

Phenotypic traits that increase fitness in a specific environment, often due to environmental pressures.
