3.29 Species Variation

VARIATION= differences in the phenotypes of individuals

--> count/measure to show the differences and how them in graphic form

- individual has a phenotype= because of genotype and the environment

- variation in the population is the variation of all individuals

-Vpop= Vgenotype + Venvironment

= surviving and living in different environments.

1- different classes or groups- variation in population, due to variation in the genotype ( environment not playing a role)

blood groups: A, AB, O, B

2- variation in population and variation in the species are cause by genetic variation (Variation in genotype) these group are modified by the environment forming a smooth curve

e.g.= height in humans- quality of diet

3- variation in population/ species

= phenotypic variation is entirely due to environmental variation

- genes have no role play in the differences that we see in the variation

e.g. home language
