Question

Briefly explain how variation for traits within species was accounted for by the view point of edios or essentialism?

Answer 1

Variation among individuals of the same species can be explained by both genetic and environmental factors. ... The set of variations of genes present, together with the interactions of genes with their environment, determines the distribution of variation of traits in a population.Any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.

Variations are classified either as continuous, or quantitative or as discontinuous, or qualitative.The variational theory of evolution has a peculiar selfdefeating property. A discontinuous variation with several classes, none of which is very small, is known as a polymorphic variation. The separation of most higher organisms into males and females and the occurrence of several forms of a butterfly of the same species, each coloured to blend with a different vegetation, are examples of polymorphic variation.there are three sources of variation:

mutation, recombination, and immigration of genes.

Mutations are the source of variation, but the process of mutation does not itself drive evolution. The rate of change in gene frequency from the mutation process is very low because spontaneous mutation rates are low . The creation of genetic variation by recombination can be a much faster process than its creation by mutation further source of variation is migration into a population from other populations with different gene frequencies..
