- Beanbag genetics is a conceptual model of genetics which was used by early Mendelians, who used to keep coloured beans in bags as a way of tracking Mendelian ratios. The phrase was first coined by Ernst Mayr in describing the work of Ronald Fisher and J. B. S. Haldane who treated genes as independent entities to simplify their mathematical analysis of population genetics. To be able to understand beanbag genetics, the meaning of population has to change. A population is no longer a group of individuals in an area but rather the alleles in an area that assort and segregate separately. All of the alleles become the gene pool. When using the beanbag approach, there are two ways that the gene pool can be viewed. The first is to view the gene pool as all the alleles that represent all the traits in the population being viewed at once. The second is to view the gene pool as only the alleles for a single trait in the population. Once the alleles are chosen for the gene pool they are selected for at random. Mayr created the name beanbag because all the alleles were thought of as beans in a beanbag. The beanbag full of beans would be considered the gene pool for the population. (en)
