range of genetic differences among organisms that allow members of the same species to have different physical characteristics
Variation in the genetic composition of individuals within or among species; the heritable genetic variation within and among populations
variation among and within species that is attributable to differences in hereditary material
means the variety of genetic information contained in the total genes of individual plants, animals and microorganisms in a place
Genetic variability found in a population of a species or all of the populations of a species Also see biodiversity, ecosystem diversity, and species diversity
The total number of genes for a given breeding population makes up its gene pool A large gene pool is genetically diverse, and therefore more likely to be healthy and robust
All of the genetic variation within a group The genetic diversity of a species includes both genetic differences between individuals in a breeding population (within-stock diversity) and genetic differences among different breeding populations (among-stock diversity)
