Forward genetics provides an unbiased approach because it relies heavily on identifying the genes or genetic factors that cause a particular phenotype or trait of interest. [ 1 ] This was initially done by using naturally occurring mutations or inducing mutants with radiation, chemicals, or insertional mutagenesis (e.g. transposable elements ).
Mouse strains can be inbred, mutated, or genetically modified, while rat strains are usually inbred. A given inbred rodent population is considered genetically identical after 20 generations of sibling-mating. Many rodent strains have been developed for a variety of disease models, and they are also often used to test drug toxicity. [14] [15] [16]
In terms of genetics, this is called an increase in allele frequency. Alleles become more or less common either by chance in a process called genetic drift or by natural selection . [ 13 ] In natural selection, if an allele makes it more likely for an organism to survive and reproduce, then over time this allele becomes more common.
A purebred Arabian horse.. A pedigreed animal is one that has its ancestry recorded. Often this is tracked by a major registry.The number of generations required varies from breed to breed, but all pedigreed animals have papers from the registering body that attest to their ancestry.
