Butterfly Populations

Groups or communities of butterflies, which can serve as indicators of environmental change due to their sensitivity to habitat and climate.

Hardy-Weinberg Equilibrium

A principle stating that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences.

Recessive Allele

Recessive allele refers to an allele that produces its characteristic phenotype only when it is paired with an identical allele (that is, in homozygous states).

Frequency-Dependent Selection

A form of natural selection where the fitness of a phenotype depends on its frequency relative to other phenotypes in the population.
