How can a gene pool be changed over time?
What processes are involved?
Processes that create change
Original population - gene pool all the variations in allele types
New gene pools that may result in groups that can't interbreed.
What processes/events change gene pools
Can change a whole gene
Block/ whole set of chromosomes
Nature/environment determining which genotypes are fit
Least influential in changing allele frequencies
Random or chance changes in allele frequencies
Individuals do not evolve but populations do
Mutations don't happen because the population doesn't need them
Most mutations are not useful
In sexually reproductive species mutations are recessive
