15.3 NOTES. Genetic Drift A random change in the frequency of an allele in a population NOT due to natural selection. More likely to occur in small populations.
SBI3U Ms. De Sousa. Biological Species: population where individuals are able to interbreed to produce viable offspring. Speciation occurs when there.
Evolution 15. The Big Idea The theory of natural selection explains evolution and the diversity of life.
