Genetic Drift Genetic drift‚ also known as allelic drift‚ is the change in the number of gene variants‚ alleles‚ in a population because of random sampling. The allele frequency in a population is the fraction of the copies of one gene that share a specific form. The alleles in the offspring are a sample of gene variants in its parents. Chance plays a part in whether one survives and carries its genes on‚ or does not. Genetic drift may cause gene variants to disappear completely resulting in reduced

Identical twins share the same genetic code and thus are natural clones. Because identical twins share all of their genes‚ it has been said that it is the environment—rather than genetics—that accounts for any differences between them. Twins can either be monozygotic ("identical")‚ meaning that they develop from one zygote that splits and forms two embryos‚ or dizygotic ("fraternal") meaning that they develop from two single eggs that are fertilized by two separate sperms. In a study design that
