3.29) Species Variation

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

Variation = differences in phenotype, by counting or measure the differences and show them in bracket form

Everyone individual has a phenotype. The phenotype is determined by the difference in genotype and environment. (continuous variation)

Different classes suggests that the variation in the species is entirely due to the variation in the genotype, with no role for the environment to play. 

For example, blood group. A, AB, B, O

Variation in the genotype can also be modified by the environment. (You can see as continuous variation) 

For example, one might inherited the genotype for being tall, but the environment such as diet also affect his height. 

Variation in population/ species that's entirely due to environmental variation. Genes have no role here. This cannot be inherited, so therefore the variation is not continuous. 

e.g.) a particular home language that you speak
