Genetic drift in small population results in fixation of a gene or loss of gene affecting only that particular population . It has no direct effect on diversity of organisms .
Decrease a population. since it may fix one allele or another at many loci in a small population. Due to chance events, all but one allele is lost at a particular locus.
The number one cause of risk to genetic diversity in populations is the size of the population. The smaller the size in an area, the less diverse genetically the population is.
Genetic diversity would increase the survival of the rat population because they would be more capable as a species of surviving in different environments.

Genetic Recombination is the exchange of genetic information in order to increase the genetic diversity of the population. Probably only with bacteria.
Stabilizing selection results in less genetic diversity in a population.

They do not use up any energy finding mates.
Genetic diversity would increase the survival of the rat population because they would be more capable as a species of surviving in different environments.
Generally, yes. To have a wide variation in a population of organisms means that your population is better able to meat environmental challenges and survive through an onslaught of parasites, such as bacteria and viruses.

The founder effect a genetic bottleneck are similar in their effect on the genetic diversity of a local population in both situations. They result in the development of a population from a small number individuals and is likely to have reduced genetic diversity.
