Thank you for the opportunity to help you with your question!

  • Population
It is the total number of personas or organisms inhabiting a given geographical area. 

  • Gene pool

Is the collection of genes in an interbreeding population that includes each gene at a certain frequency in relation to its alleles

  • Microevolution

It  is evolutionary change involving the gradual accumulation of mutations leading to new varieties within a species.

  • Mutation

Refers to the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes

  • Genetic drift is the variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce
  • Founder effect  is the the reduced genetic diversity that results when a population is descended from a small number of colonizing ancestors.

Please let me know if you need any clarification. I'm always happy to answer your questions.

  • Gene flow
It is the alteration of the frequencies of alleles of particular genes in a population,resulting from interbreeding with organisms from another population having different frequencies.

  • Nonrandom mating
It is a mating pattern and a form of sexual selection in which individuals with similar genotypes and/or phenotypes mate with one another more frequently than would be expected under a random mating pattern.

  • Natural selection this is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
