A hybrid between two inbred strains can be used to cancel out deleterious recessive genes resulting in an increase in the mentioned areas. This is known as heterosis. [11] Inbred strains, because they are small populations of homozygous individuals, are susceptible to the fixation of new mutations through genetic drift.
Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a genetic identity closer to that of the parent.
The origins and history of recombinant inbred strains are described by Crow. [1] While the potential utility of recombinant inbred strains in mapping analysis of complex polygenic traits was obvious from the outset, the small number of strains only made it feasible to map quantitative traits with very large effects (quasi-Mendelian loci).
The Wistar rat, which was the first developed rat model strain. A laboratory mouse or rat strain is a group of animals that is genetically uniform. Strains are used in laboratory experiments. Mouse strains can be inbred, mutated, or genetically modified, while rat strains are usually inbred. A given inbred rodent population is considered ...

Cannabis strains is a popular name to refer to plant varieties of the monospecific genus Cannabis sativa L.. They are either pure or hybrid varieties of the plant, which encompasses various sub-species C. sativa , C. indica , and C. ruderalis .
[19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3] Attempts to produce a Cannabis strain with a shorter growing season are another application of cultivating C. ruderalis. [8] C. ruderalis when crossed with sativa and indica strains will carry the recessive autoflowering trait ...
