Genetic variability. Definition. noun. (1) The tendency of individual genetic characteristics in a population to vary from one another. (2) The potential of a genotype to change or deviate when exposed to environmental or genetic factors. Supplement.
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. DNA damage can cause an error when the DNA is replicated, and this error of replication can cause a gene mutation that, in turn, could cause a genetic disorder. DNA damages are repaired by the DNA repair system of the cell.
