What cellular events occur in the G1 phase of the cell division cycle? - normal growth and cell function What is the best way to describe homologous chromosomes? - they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - Darwin's theory of natural sel...
