heterozygosity
This term is a technical descriptor used primarily in genetics and evolutionary biology. It describes a specific genetic state or a statistical measurement of genetic variation within a population. Because it refers to a biological condition or a mathematical proportion, it is treated as an abstract concept.
As an uncountable noun, it does not have a plural form. It is typically used in academic or clinical contexts to discuss genetic diversity, inbreeding depression, or population viability. It is distinct from "heterozygous," which is the adjective describing an individual organism.
Meanings
