Founder effect and genogeography of CV- and BL-mutations in black-and-white cattle

详细

The results are obtained by simultaneous diagnostics of mutant CV- and BL-alleles. Five groups of animals–carriers and noncarriers of mutations are identified. In Russia the mutant CV-alleles are met more frequently because of the intensive use of their carriers. While elimination of BL-allele was started earlier due to developed methods, the diagnostics of CV-mutations has been undertaken later. Propagation of missense-mutations in the world and the Russian Federation has been occurring through the breeding bulls and cows–carriers. Initially spermobanks and, afterwards, cows were reserves for the diagnosed BLand CV-mutations.
