You are very close! The Hardy-Weinberg principle actually states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

Here's a breakdown of the key parts:

* Allele and genotype frequencies: This refers to the proportions of different alleles (versions of a gene) and combinations of alleles (genotypes) within a population.

* Remain constant: This means that the frequencies of these alleles and genotypes will not change over time.

* Absence of other evolutionary influences: This is the crucial part. The principle only holds true if certain conditions are met. These conditions are:

* No mutations: Mutations introduce new alleles, changing the gene pool.

* No gene flow: Migration into or out of the population can alter allele frequencies.

* Random mating: Non-random mating patterns (like inbreeding) can change genotype frequencies.

* No genetic drift: Random fluctuations in allele frequencies, especially in small populations, can disrupt the equilibrium.

* No natural selection: Differential survival and reproduction based on traits can alter allele frequencies.

In essence, the Hardy-Weinberg principle is a theoretical baseline for understanding how populations evolve. It highlights the factors that can cause genetic change and allows us to measure the relative impact of these factors in real-world populations.
