Biology notes: Natural Selection: Mutation mecanism of change. Gene-flow Genetic drift Non-random mating *A mutation can be either negative or neutral. It could be positive but the rate is very low. A geneflow is the exchange in between 2 populations. genetic drift It needs an event to occur, sinu benefits or perjucdative things could happen to the especies. non-random mating relates to genetic drift since species could mate to produce more populations. There are 88 people on this farth Founder effect groups who learned how to keep the population In genetic chift we can observe the bottleneck example in which they lose species and mate with the ones lett. *This affects move on tosker species benuse they dre at nok of extintion
