What does the allele frequency have to total in the hardy- weinberg equilibrium?

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.:

from Penn Foster

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
