Except in certain rare circumstances, such as new mutations or uniparental disomy, both parents of an individual with such a disorder will be carriers of the gene. These carriers do not display any signs of the mutation and may be unaware that they carry the …
WebInbreeding. Inbreeding can lead to higher frequencies of genetic defects. Inbreeding occurs when the alleles at a gene site are identical by descent. This can occur when a common ancestor appears on both the maternal and paternal side of the pedigree. In recent years, dairy bulls with high genetic merit for performance traits have been used ...
