Definitions:

Somatic Mutation

A somatic mutation is a mutation that affects cells in the body (“soma”) of an organism. These mutations affect all the daughter cells produced by the affected cell and can affect the phenotype of the individual. In animals, somatic mutations are not passed down to offspring. In plants, somatic mutations can be passed down during vegetative reproduction.

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.
