Imagine a species of randomly mating rodents living on an island. As the sea levels increase the low-lying center of the island gets flooded so that the island is now cut in half and there is no way for the animals on one side of the flooded region to cross over onto the other side; effectively turning one island into two islands. What would you expect to happen to these populations over time.

Group of answer choices
A. Heterozygosity in each subpopulation would decrease.
B. Heterozygosity in each subpopulation would increase.
C. Fst would decrease.
D. Fst would increase.
A. Heterozygosity in each subpopulation would decrease.
As species is seprated between two differnt groups then eventually inbreeding will be occue between them as result Heterozygosity would be decreased.
C. Fst would decrease.
Fst is the ratio of the total genetic variance present in the population, as speices is divided into two different group hence Heterozygosity will decrease and due to which variation would also decrease and hence Fst would be decrease

FISCAL POLICY IN THEORY: March, 2020: we are on the verge of Congress and the President passing legislation that will empower the federal government to spend an unprecedented amount of EXTRA money not seen since World War 2 ---- in order to address the pandemic but also to help cushion the blow financially of perhaps ten or twenty million Americans --- or more --- losing their jobs, and thus suffering a drop in income.
