Mutation
A bottleneck can lead to a significant reduction in the genetic diversity of a population, causing certain alleles to be lost and others to become more common. This can increase the frequency of rare alleles and result in genetic drift, potentially leading to an increase in genetic diseases or reduced fitness in the population.
In small populations, genetic drift can have a greater impact on allele frequencies, leading to more rapid changes than in large populations where genetic drift has a smaller effect. Additionally, in small populations, the effects of genetic drift can increase the likelihood of alleles being lost through random sampling.
If someone from outside of your gene pool were to have a child inside of your population, it could possibly affect the gene pool of your population. If someone from Alaska had a child in Mississippi it would affect the gene pool of Mississippi.
The collection of all the genes in a population is called the gene pool. This gene pool contains all of the genetic variation within a population, which can be passed on to future generations through reproduction.
When a population is not evolving, it means that the allele frequencies within the population are remaining stable over generations. This could occur if the population is experiencing no mutations, no gene flow, no genetic drift, no natural selection, and if mating is completely random. In essence, the population is in Hardy-Weinberg equilibrium.
Mutations are changes in the DNA sequence that can create new alleles by introducing variations in the genetic code. These new alleles can then be passed on to future generations, leading to genetic diversity within a population.
by introducing new alleles
Interbreeding can increase genetic diversity by introducing new alleles into a population. This can potentially lead to a broader range of phenotypic traits and increase the population's ability to adapt to changing environments. However, excessive interbreeding can also lead to inbreeding depression, which reduces overall fitness due to increased expression of deleterious alleles.

The distribution of alleles in a population - APEX
Mutations contribute to genetic variation within a population by introducing new alleles. These new alleles can lead to different traits or characteristics, increasing diversity within the population. Over time, natural selection can act on this variation, influencing which traits become more or less common.
