A
group of same species in a particular place at a particular time
3

A
how often allele of gene occurs in population
4
Q
migration
A
causes gene flow and changes in allele frequency
- movement of people from one area to another with intention of permanent settlement
5
Q
gene flow
A
transfer of alleles/genetic info from one population to another
- facilitated by migration, inhibited by barriers
- brings alleles not already in population
