| Abstract | The alpha-hemoglobin chains in adult deer mice are usually encoded by two tightly linked loci. Because of strong linkage disequilibrium, almost all alpha-globin haplotypes fall into just two classes. The a0c0 class predominates in high-altitude populations, whereas the a1c1 class is generally fixed in low-altitude populations. Here we show that the alpha-globin genotype has effects at both the biochemical level [on blood oxygen affinity (P50)]and at the level of whole-animal physiology [on maximum rate of oxygen consumption (VO2max) during both exercise and cold exposure]. The a1c1/a1c1 genotype mice have the highest P50 values and show the highest Vo2max values at low altitude (340 m) but the lowest VO2max values at high altitude (3800 m). The a0c0/a0c0 mice have the lowest P50, and show the highest VO2max at high altitude but usually have the lowest VO2max at low altitude. The a0c0/a1c1 heterozygotes have an intermediate P50 and are generally intermediate in VO2max at both altitudes. Since high VO2max is advantageous for aerobic exercise and thermogenesis, the physiological data provide a potential explanation for the correlation of haplotype frequencies with altitude. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
