What are the three types of evolutionary mechanisms?
Give this one a try later!
There can be no difference in the survival and reproduction of individuals
Populations may not be added to or subtracted from by migration
There can be no mutation
The population must be sufficiently large to prevent sampling errors
Individuals mate at random
, -selection
-genetic drift
-gene flow
-habitat loss
-climate change
-invasive species
-overexploration
-pollution
-they can mate

change in the genetic
composition of a population competition within genders
from one
generation to the next
form of directional selection
where given traits are change in the populations'
selected for by humans allelic frequency due to a
random event
