A gene drive is a natural process [1] and technology of genetic engineering that propagates a particular suite of genes throughout a population [2] by altering the probability that a specific allele will be transmitted to offspring (instead of the Mendelian 50% probability). Gene drives can arise through a variety of mechanisms.

Gene duplication is a major mechanism through which new genetic material is generated during molecular evolution. For example, the olfactory receptor gene family is one of the best-documented examples of pseudogenes in the human genome. More than 60 percent of the genes in this family are non-functional pseudogenes in humans.
Fixation rates can easily be modeled as well to see how long it takes for a gene to become fixed with varying population sizes and generations. For example, The Biology Project Genetic Drift Simulation allows to model genetic drift and see how quickly the gene for worm color goes to fixation in terms of generations for different population sizes.

Daisy chaining DNA is a form of gene editing, or "gene drive", which, unlike CRISPR, is self-limiting. This means that any alteration made in the laboratory to a gene sequence is limited to a local population only, and cannot be passed on to global populations. It occurs when DNA undergoing PCR amplification forms tangles that resemble a 'daisy ...
Listed below are some notable groups and populations from South Asia by human Y-chromosome DNA haplogroups based on various relevant studies.. The samples are taken from individuals identified with specific linguistic designations (IE=Indo-European, Dr=Dravidian, AA=Austro-Asiatic, ST=Sino-Tibetan) and individual linguistic groups, the third column (n) gives the sample size studied, and the ...
The gene is a unit of hereditary information that exists in many physical copies in the world, and which particular physical copy will be replicated and originate new copies does not matter from the gene's point of view. [20] A selfish gene could be favored by selection by producing altruism among organisms containing it.
