It increases genetic diversity by introducing alleles from one population into another.
<span>Speciation is the formation of new species as a result of evolution these three stages are (separation, adaptation, and reproductive isolation.)</span>
I think it is pitch I am not 100% sure
Competition
- when space is full pack organisms compete for resources and the sooner the
resources are gone. Predation - organisms feed on and kill animals lowering
their population growth and the prey population growth, same as herbivore and
human prey. Disease - again feeds on hosts. Stress from overcrowding - females
could kill offspring. Hurricanes (density-independent limiting factors).
The mouse's offspring are more than likely either not going to survive birth and or be deformed
