F_st can be used to measure the number of migrants per gegenetration by measuring the balance between the effects of two causes of evolution. Name the two causes AND effects they have on variation within AND amongst the population

#1

Cause: _____

Effect within population on genetic variation: ______

Effect between population on genetic variation: ______

#2

Cause: _____

Effect within population on genetic variation: ______

Effect between population on genetic variation: ______

Solution

1. cause:DRIFT

Effect within population on genetic variation:The people within population are less

Effect between population on genetic variation:The number of people affected are more as they disperse

2.cause: MIGRATION

Effect within population on genetic variation:The genes decrease over a period of time.

Effect between population on genetic variation:The genes moving are increasing with time.
