Germline Mutation

A germline mutation is a mutation that affects the gametes (eggs, sperm) of an individual and can be transmitted from parents to offspring. Germline mutations create the heritable genetic variation that is relevant to evolution.

Frameshift Mutation

A genetic mutation caused by insertions or deletions of a number of nucleotides that is not divisible by three, leading to a shift in the reading frame of codons and potentially altering protein function.

Phenotypic Plasticity

The potential of an organism to transform its observable traits in adaptation to environmental variations.

Genetic Polymorphisms

The occurrence of two or more distinct forms of a gene within a population, contributing to genetic diversity.
