The scientists from the Institute of Zoology under the Chinese Academy of Sciences sequenced the genomes of three panda families connected with Qizai, as well as other 29 pandas in black and white check. They found that the mutation in a gene called Bace2 that encodes a precursor protein's c...
Genetic variation, which is generated by mutation, recombination and gene flow, can reduce the mean fitness of a population, both now and in the future. This ‘genetic load’ has been estimated in a wide range of animal taxa using various approaches. Advances in genome sequencing and computatio...

This disease is probably a hereditary disorder considering the strong breed predisposition. Despite...
Great progress has been made in two technologies related to biomedical research: (1) manipulating the genomes of cells; and (2) inducing stem cells in culture to differentiate into potentially useful cell types. These technologies can be used to create animal models of human disease and to provi...
A total of 43 mutation sites were detected, including 40 transitions and 3 transversions. Fu's test of selective neutrality showed that the sheep populations had no population demographic expansion (0.10 > > 0.05). The different clustering methods, namely neighbor-joining, minimum evolution, and ...
If a mutation in a gene is not known to cause human disease but exhibits a strong deficit of homozygosity it can, in theory, be due to any event from early embryonic selection to sickness in adults that prevents them from participation in research. If variants with a strong deficit of ...
Furthermore, a disease-causing mutation in Crygc (Crygc -/- ) that pre-existed in SSCs could be readily repaired by CRISPR-Cas9-induced nonhomologous end joining (NHEJ) or homology-directed repair (HDR), resulting in SSC lines carrying the corrected gene with no evidence of off-target ...
