negative selection
I think it may be natural selection, which eliminates individuals with harmful traits and genes from the gene pool because they are less likely to survive or reproduce. However, if it is a genetic function you are talking about I don't know. Try finding a more reputable source if that is the case.
negative selection.
negative selection
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Gene flow
Alleles
Alleles are the specific form of a gene e.g. gene for 'eye colour, allele for 'blue eyes'. Therefore the alleles are in the genes.
they both show something about appearance.

negative selection.
Segregation
Different versions of the same gene are called
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
Gene flow
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
negative selection.
There isn't ONLY one way, except for genetic manipulation (from an injected virus which is NOT for immunization); the only other way is via reproduction.
