Question

A population of 1000 dung beetles was split into five populations when irrigation canals were built through their habitat. The five new populations were called the Northern, Southern, Eastern, Western, and Central populations. Each new population consisted of about 200 individuals. The five populations continued to evolve, and no migration occurred among populations. One hundred generations later, each population still has about 200 individuals, and a biologist investigates them. Would a biologist agree or disagree with the following statements? In smaller populations of 200 individuals the process leading to genetic drift could have a stronger influence on a gene than natural selection. A-agree B-Disagree

Explanation / Answer

Disagree-------------answer

================

Evolution in the population....usually occurs as a result of migration, mutation, natural selection, genetic drift, sexual and artificial selection.

Evolution simply means changes.

The populaces were detached from each other so GENTIC DRIFT couldn't bring about the populaces to change

SO i disagree
