States that allele frequencies in a population are constant unless a factor causes change
Hardy Weinberg principle
States that allele frequencies in a population are constant unless a factor causes change. Hardy Weinberg principle. The Hardy-Weinberg principle explains how the genetic makeup of a large, random-mating population will stay the same over generations unless influenced by outside factors.

When population growth starts slow, then sees exponential growth, then slows again
Logistic growth
When population growth starts slow, then sees exponential growth, then slows again. Logistic growth. In simple terms for Grade 8, logistic growth is how a population grows quickly at first, then slows down as resources run out.
