Genetic variation is the result of mutation, gene flow between populations and sexual reproduction. In asexually reproducing organisms, some genetic variation may still result from random mutation. More »

The two main sources of genetic variation are mutations and recombinations of genes as a result of sexual reproduction. A mutation is a permanent change in the DNA within a gene. More »

Homologous chromosomes have the same genes, gene order and approximate length in common. A gene's location is called its loci. For every gene that exists at a certain loci on one homologous chromosome, the same gene exis... More »

There are at least three different genes that can produce blue eyes in cats: the dominant white gene, the recessive white gene associated with color points and the white-spotting gene. All of these genes affect the produ... More »
