WebGenetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time. Function Anatomy WebSolved by verified expert. Phenotypic variance is a measure of the variability that can be found within a population of organisms depending on the phenotypes of those species. It is frequently applied to the task of determining the degree to which people within a community differ genetically from one another.
