Document Summary
Before darwin, variations in species were unimportant because the choice of this difference was ultimately because of the divine. After darwin ( on the origin of species - 1859 ), variation was recognized because it lies at the heart of evolution and natural selection. Phenotype - an observable trait attributed to alleles/genotype (genetic makeup) and. Population genetics - study of patterns of genetic variation in natural populations. Populations - groups of interbreeding organisms that are of the same species and also in the same area. Humans are not as different as other species, two humans share same dna makeup inferences about evolution from patterns of variation. environment. 99. 9% because the mutation is from one cell and its descendant is the mutated product. Species - capable of interbreeding and thus sharing genetic makeup / allele . These alleles are from the gene pool (phenotypes and others - hair type color etc) and are random/different.
