Variability is a measure of the spread of a data set. Learn more about the different measures of variability including the range, variance, and standard deviation, and how they are used in the field of Psychology.
Genetic variability (vary + liable-to or capable of change) is the ability, i.e. capability of a biological system â individual and population â that is changing over time. The base of the genetic variability is genetic variation of different biological systems in space.Genetic variability is a measure of the tendency of individual genotypes in a population to vary from one another, also.Variability is different from genetic diversity, which is the amount of variation seen in a particular population. Homologous recombination is a significant source of variability. 2  During meiosis in sexual organisms, two homologous chromosomes from the male and female parents cross over one another and exchange genetic material.
