Description:
Meiotic recombination creates genetic diversity and ensures segregation of homologous chromosomes. Previous population analyses yielded results averaged among individuals and affected by evolutionary pressures. We sequenced 99 sperm from an Asian male by using the newly developed amplification method-multiple annealing and looping-based amplification cycles-to phase the personal genome and map recombination events at high resolution, which are nonuniformly distributed across the genome in the absence of selection pressure. The paucity of recombination near transcription start sites observed in individual sperm indicates that such a phenomenon is intrinsic to the molecular mechanism of meiosis. Interestingly, a decreased crossover frequency combined with an increase of autosomal aneuploidy is observable on a global per-sperm basis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3590491/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3590491/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Sijia -- Zong, Chenghang -- Fan, Wei -- Yang, Mingyu -- Li, Jinsen -- Chapman, Alec R -- Zhu, Ping -- Hu, Xuesong -- Xu, Liya -- Yan, Liying -- Bai, Fan -- Qiao, Jie -- Tang, Fuchou -- Li, Ruiqiang -- Xie, X Sunney -- HG005097-1/HG/NHGRI NIH HHS/ -- HG005613-01/HG/NHGRI NIH HHS/ -- R01 HG005097/HG/NHGRI NIH HHS/ -- RC2 HG005613/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 21;338(6114):1627-30. doi: 10.1126/science.1229112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23258895" target="_blank"〉PubMed〈/a〉
