Question

Explain Fst and the answer please!

Populations of the Florida panther were reduced to very low levels in the second half of the twentieth century. In 1968 Alligator Alley, an extension of a major highway, divided the population into a northern and southern populati estimate the N e of the population to be 75 individuals on either side of the highway, and measure an F ST of 0.30, what can we conclude about the effect of the highway? O The environment has been divided into subregions too small to support large numbers of territorial cats. O The highway severely blocks the southern population, allowing only a tiny amount of gene flow. O The highway is not a barrier to the cats at all, and the regions north and south of the highway act as a single. well-mixed population O The highway completely isolates the southern population, allowing no gene flow. The highway only hinders migration a little bit and gene flow is maintained at a relatively high rate.

Explanation / Answer

the highway has blocked the population from inter mixing as a result the gene flow has reduced to Fst=0.30

FST measures the amount of genetic variance that can be explained by population structure

This comparison of genetic variability within and between populations is frequently used in applied population genetics. The values range from 0 to 1. A zero value implies complete panmixis; that is, that the two populations are interbreeding freely. A value of one implies that all genetic variation is explained by the population structure, and that the two populations do not share any genetic diversity.
