  2. 1. Evolutionary Studies of the Mammalian Y Chromosome

    Author : Linda Hellborg; Hans Ellegren; Terry Burke; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Y chromosome; field vole; cattle; selection; primer design; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : 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. READ MORE

  4. 2. Mosaic loss of chromosome Y : methods for detection and consequences for affected leukocytes and men

    Author : Marcus Danielsson; Lars A. Forsberg; Ståhl Patrik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mosaic loss of chromosome Y; mLOY; somatic mosaicism; Medicinsk genetik; Medical Genetics;

    Abstract : 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. READ MORE

  5. 3. The role of hematopoietic chromosome Y loss in health and disease

    Author : Jonas Mattisson; Lars A. Forsberg; Jonatan Halvardson; Adam Ameur; Andrea Ganna; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; loss of chromosome Y; LOY; mosaic loss of chromosome Y; mLOY;

    Abstract : Mosaic loss of chromosome Y (mLOY) is the most common somatic mutation, and affected men have increased risk for all major causes of death, including cardiovascular diseases and cancer. As a male specific mutation, it helps explain why men live shorter lives than women. READ MORE

  6. 4. Analysis of the origin and spread of the domestic dog using Y-chromosome DNA and mtDNA sequence data

    Author : Mattias Oskarsson; Peter Savolainen; Ben Sacks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mtDNA; domestication; Y-chromosome; SNP; ASY; dog; dingo;

    Abstract : 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. READ MORE
