The endocrine component of the pancreas consists of islet cells (islets of Langerhans) that create and release important hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar.
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.The variability of a trait describes how much that trait tends to vary in response to environmental and genetic influences. 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.
