evolution quiz

what is gene flow

• movement of alleles between population

• genes from organisms

• genetic waterfall

when does gene flow occur

• by having offspring

• when individuals join new populations and reproduce

• when organisms reproduce

Genetic drift causes a loss of genetic diversity

• true

• false

The isolation of population can lead to speciation

• True

• False

which isn't a negative effect genetic drift has in population

• less likely to have some induvial that can adapt 

• harmful alleles can become more common due to chance.

• can't create offspring

geographic barriers can cause

• barriers

• offsrping

• isolation

• population

Reproductive isolations can occur between

• isolation populations

• isolation

• barrier's

• populations
