There are three different types of natural selection and all three types affect the frequency of alleles in a population. by analyzing the graphs above, determine which type of natural selection is matched correctly to the effect it has on allele frequencies in populations for certain traits.

All options are matched correctly

Explanation:

In a stabilizing selection, the individuals are produced with most average and common traits. It is a selection type that is linked to phenotypic trait. In the case of stabilizing selection, the genetic variance decreases and an average phenotype is favored against the extreme variations.  

In directional selection, phenotypes lying at one end of spectrum are selected. This is the case of peppered moth in England. This selection shifts the genetic variance towards phenotypic characteristics that is fit and adaptable to the changing environment.  

In disruptive selection, two or more different types of phenotype are selected in such a way that phenotypes at the extremes are more fit while the phenotypes in the mid are less fit.

Hence, all the options are matched correctly.

looks like youre on your own with this one buddy

the answer is c. altitude. hope this ! #brainiac
