Sammanfattning : Sex chromosomes are useful in elucidating the evolutionary factors affecting diversity and divergence. In particular, Y chromosome analyses may complement studies using mitochondrial DNA for inferring sex-specific population genetic processes. LÄS MER
2. Mosaic loss of chromosome Y : methods for detection and consequences for affected leukocytes and men
Sammanfattning : It has been known for centuries that men live shorter lives than women, but until recently, the biological mechanisms driving this sex bias has been poorly understood. Mosaic loss of chromosome Y (mLOY) refers to chromosome Y aneuploidy, a male specific and the most common somatic mutation in human blood cells. LÄS MER
3. Analysis of the origin and spread of the domestic dog using Y-chromosome DNA and mtDNA sequence data
Sammanfattning : The domestic dog was probably the first domesticated animal, and the only one to spread to all continents in ancient times. The dog is one of the most phenotypically diverse animals, a result of human selection throughout dog history. LÄS MER
4. Colonization history of Fennoscandian field voles (Microtus agrestis) : geographic structure of mitochondrial DNA and Y chromosome variation
Sammanfattning : .... LÄS MER
Sammanfattning : Our ability to map and sequence whole genomes is one of the most important developments in biological science. It will provide us with an unprecedented insight into the genetic background of phenotypic traits, such as disease resistance, reproduction and growth and also makes it feasible to study the processes of genome evolution.
