Human populations show genetic diversity from "summary" of Human Biology by Cecie Starr,Beverly McMillan
Genetic diversity is a fundamental characteristic of human populations. This diversity arises from the fact that humans have a large number of genes, each of which can exist in multiple forms. These different forms of a gene are called alleles. As a result, individuals within a population can have different combinations of alleles for a given gene. This genetic diversity is further increased by the fact that genes are inherited from both parents. Each parent contributes one allele to their offspring, leading to even greater variability in the genetic makeup of individuals. Additionally, genetic diversity is also influenced by factors such as mutations, gene flow, and genetic drift. Mut...
