Since prokaryotes can only reproduce asexually gene swapping is a way for them to create genetic diveresity.
Gene swamping is essentially the extinction of a smaller population by a larger population. The larger population (humans, animals, plants -- anything living and reproducing) overwhelms the smaller population, genetically absorbing it. It is an anthropological/biological term, but has been applied to other situations as well, such as the gene swamping of tri-racial isolate communities. For an excellent description/discussion of gene swamping, check out UIC's (Univesity of Illinois Chicago) web site on conservation genetics. Under "Classes, BIOS 101" they have an excellent PowerPoint presentation that explains it better than I can. http://www.uic.edu/classes/bios/bios101/consgenetmurray.PPT.
The operon often controls the transcription of prokaryote genes.
The entire collection of genes among a population is called the "gene pool".
Gene flow
Prokaryote mostly contain a single large DNA molecule (circular chromosome) while eukaryotes contain multiple linear chromosomes. Most prokaryote are haploid that means they contain only one copy of each gene.
1.Which does not add new alleles to a population gene pool?
A gene pool is the total number of genes of every individual in an interbreeding population. Which is like having every single gene of a population into one big pool (population).
gene drift is when a population experiences a decrease in variation and population size.
1.Which does not add new alleles to a population gene pool?
changes in a population's gene pool.
The combined genetic information of all members of a particular population is the population's gene pool. This gene pool contains all of the genetic variations that exist within the population, which can influence the population's ability to adapt to environmental changes and evolve over time.
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.
