Final answer:
A population needs no mutation, no gene flow, large size, random mating, and no natural selection to be modeled by Hardy-Weinberg dynamics, which indicate a non-evolving equilibrium state.
Step-by-step explanation:
For a population to be accurately modeled by Hardy-Weinberg dynamics, it must have the following properties:
- No mutations occurring in the gene pool.
- No migration or gene flow into or out of the population.
- A very large population size to minimize genetic drift.
- Random mating to ensure no selective breeding.
- No natural selection, meaning every individual has an equal chance of survival and reproduction.
Under these conditions, the population is considered to be in Hardy-Weinberg equilibrium, and the allele and genotype frequencies will remain constant from one generation to the next, indicating that evolution is not occurring.
