- Ө ғң ә ө ә ң қ Variability property of living organisms to acquire new characteristics under the influence of environmental factors
() - (қ)ө-қ ң ә қ құң ө ң ө Phenotypic (odification) variability - hanges in phenotype due to the influence of external environmental factors without changing the structure of genotype
. ң ғ ә ң ө Phenocopies changes of phenotype due to the influence of adverse environmental factors.
- , . ү ң ң өң . Genocopies - the same changes of phenotype controlled by alleles of different genes.
- (), . қ ң қ ғ ү ә ұққ ө () Morphosis- non-hereditary changes (modifications) caused by environmental factors that are extreme or unusual for a species
() , . ұққ ө () ң ң ө қ, қ ө ұқ Hereditary (genotypic) variability appears to change the genotype of the individual, therefore, is transmitted by sexual reproduction descendants.
, () . ө - ғ ң ң ү ү ұқ ө Combinative variability - is the variability of offspring due to the appearance of new combinations of the genes of parents.
- қ ң ұқ ө Mutation persistent change of genetic material
- , . () ( ) . ғ ә Mutagenic factors factors causing mutation. Distinguish natural and artificial (human-induced) mutagenic factors
ң Қ ғ қ ү қ қ қ Reparation the ability of cells to correct damages and breaks in DNA molecules  
, ү ә ә ө қ ң ғ Қ-ғ ө Pyrimidine dimers -DNA defect that occurs due to the formation of a covalent bond between two adjacent pyrimidine bases under the action of ultraviolet rays
á , -. ә ә Қ-ғ өң ө қ ә қ Fotoreaktivátsiya -one of the recovery mechanisms visible light of DNA damage caused by UV radiation.
қ - Қғ қғ ң ә Қ ң қ қ қ Exisional reparation - reparation chacterising by removing of damaged nucleotides of DNA with subsequent restoration of the normal structure of the molecule of DNA
, қғ қғ Қ қ қ Postreplicative reparation reparation of damages of DNA revealed after replication
