Natural selection. Changing gene frequency. Anthony Allison
discovered 30% population of Lake Victoria had sickle cell anaemia. But less than 1% in highlands where normal area.
deme = local population of organisms with similar genes who interbreed and produce offspring..
population genetics is the study of changes in genetic material specifically the changes in frequency of alleles.
s small scale evolution such as changes in sequence from one generation to the other. macroevolution is large-scale evolution such as speciation that occurs after long period.
Study populations, diseases, genome, risks, changes.
