Genetic Diversity and Admixture in Three Native Draught Horse Breeds Assessed Using Microsatellite Markers
population structure endangered breeds gene flow genetic distances
2018/3/5
In this study, we aimed to estimate and compare genetic diversity of two native draught horse breeds and check
the possible influence of Noriker breed population on these native breeds. Genetic analy...

Three-way dance herbivores plants microbes unveiled
2017/3/14
What looks like a caterpillar chewing on a leaf or a beetle consuming fruit is likely a three-way battle that benefits most, if not all of the players involved, according to a Penn State entomologist....
Genetic diversity within and gene flow between three draught horse breeds using genealogical information
genetic drift inbreeding Silesian Noriker Noriker Czech-Moravian Belgian horse
2016/11/11
Three draught horse breeds are maintained in the Czech Republic: the Silesian Noriker (SN), the Noriker (N), and the Czech-Moravian Belgian (CMB). Because the SN and CMB populations are currently clos...

PREDICTING NUCLEAR GENE COALESCENCE FROM MITOCHONDRIAL DATA: THE THREE-TIMES RULE
molecular systematics monophyly whales
2015/12/17
Coalescence theory predicts when genetic drift at nuclear loci will result in fixation of sequence differences
to produce monophyletic gene trees. However, the theory is difficult to appl...

Two new studies from UC Berkeley should give scientists who use CRISPR-Cas9 for genome engineering greater confidence that they won’t inadvertently edit the wrong DNA.The gene editing technique, creat...
COMPUTING HOPF BIFURCATIONS II: THREE EXAMPLES FROM NEUROPHYSIOLOGY
Hopf bifurcation resultant bialternate product neuron model
2015/8/25
In a previous paper [11] we presented algorithms for detecting Hopf bifurcations in
two-parameter families of vector elds based on classical algebraic constructions. In addition to their
utility as...
