3.29 Species Variation

understand that a variation within a species can be genetic, environmental or a combination of both.

Variation = differences of phenotype count/measure
Individual Phenotype = genotype + environment
Variation in population = Variation Genotypes (environment = 0)
E.g. Blood group A, AB, B, O = Discontinuous variation
Variation Population = variation genotype + variation environment eg. height = continuous variation.
Variation Population = (genotype =0) + variation environment eg. language not inherited
