Respuesta :

In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1. ... In population genetics studies, the Hardy-Weinberg equation can be used to measure whether the observed genotype frequencies in a population differ from the frequencies predicted by the equation.

Hope this helps

Answer:

1. directional selection

2. Hardy-Weinberg equilibrium

3. sympatric

4. This is allopatric speciation.

5. This is an example of stabilizing selection in a population because the organisms in the middle of the population have the best fitness for their environment.

6. The five conditions impacting this equilibrium are: mutations, nonrandom mating, genetic drift, migration, and natural selection.

7. Natural selection impacts single-gene traits because of the possible extinction of one trait or increase of another trait. If a trait is found to be not preferable in that environment, it could be eliminated through natural selection.

8. The total allele frequency in the Hardy-Weinberg equilibrium has to equal 1.:
