House mouse (Mus musculus) Gene of interest: B4galnt2 (encodes glycosyltransferase enzyme) Allele R: Associated with prolonged bleeding due to issues with blood clotting; associated with resistance to bacterial infections due to absence of intestinal expression. Allele C: Associated with increased susceptibility to bacterial infections; not associated with prolonged bleeding. A B с The population is closed; there are no new mice coming in. The cages are setup to allow for random mating. The B4galnt2 gene is not associated with any mating preferences or non-random mating patterns. Studies have shown that mutations in this locus are extremely rare. The population is EXTREMELY large. The population is kept in well maintained environment, free of bacterial infections. The mouse food is supplemented with a low dose of blood coagulator, which helps the blood clot and eliminates any prolonged bleeding. None of the genotypes display any side effects to this medication. The population is closed; there are no new mice coming in. The cages are setup to allow for random mating.
