Final answer:
The model of mating from which Hardy-Weinberg Equilibrium is derived indeed assumes a population is infinite in size, which is true. This assumption helps ensure that allele frequencies remain constant across generations, provided other conditions are also met.
Step-by-step explanation:
The statement that the Hardy-Weinberg Equilibrium is derived from a model that assumes a population is infinite in size is true. The Hardy-Weinberg principle operates under a set of ideal conditions, one of which is a very large population size, conceptualized as being infinite.
The principle outlines that allele frequencies and genotype proportions in a population will remain constant from one generation to the next if certain conditions are met. These conditions include no mutation, no migration, a very large population size, random mating, and no natural selection.
While no real population can perfectly satisfy an infinite population condition, it is a theoretical requirement to ensure that the genetic drift (random fluctuations in allele frequencies) is negligible, which is more likely in very large populations.
