Final answer:
The false statement regarding the Hardy Weinberg principle is that the gene pool remains constant (B), as allele frequencies in a population only remain constant under specific conditions which are rarely met in nature; evolution constantly influences the gene pool.
Step-by-step explanation:
Considering the Hardy Weinberg principle, the false statement is B) Gene pool remains a constant. This is because the Hardy Weinberg principle stipulates that allele frequencies in a population will remain constant from generation to generation only in the absence of other factors such as natural selection, mutation, genetic drift, and migration (gene flow). In reality, these factors are always at play, thus causing changes to the gene pool. Therefore, the gene pool does not remain strictly constant, as evolution is an ongoing process.
The correct statements are: A) Allele frequency varies from species to species, C) The Hardy Weinberg principle uses algebraic equations to predict allele frequencies, and D) The frequency of alleles is expected to remain fixed through generations under the specific conditions of the Hardy-Weinberg equilibrium. However, since these conditions are rarely met, allele frequencies are typically changing, which is indicative of evolutionary processes occurring.
