Gene pool that is the sum of populations at a given time , that is a population is made up of individuals of the same species and includes all genes and combination of genes sum of allele in the population.

- Over generation small changes in the amount of each type of gene can happen for a number of reasons. Gene mutation: an error during cell division can create a new type of gene. Genetic drift : the amount of each gene in gene pool can change over time because of change events.
-A Gene pool is not a real , it's an abstract idea or an imaginary collection like imagine you wake up one morning after a zombie apocalypse , there are only 100 people's still live on earth and none of the survivors have freckles. Is it possible that the gene for freckles is completely gone from the human genome pool
- If people mate randomly , and there's no advantage or disadvantage to perticular genes, then into gene pool will likely stay the same over time.
