Major histocompatibility complex variation in the endangered Przewalski's horse.
The major histocompatibility complex (MHC) is a fundamental part of the vertebrate immune system, and the high variability in many MHC genes is thought to play an essential role in recognition of parasites. The Przewalski's horse is extinct in the wild and all the living individuals descend from 13 founders, most of whom were captured around the turn of the century. One of the primary genetic c...
متن کاملMicrosatellite and major histocompatibility complex variation in an endangered rattlesnake, the Eastern Massasauga (Sistrurus catenatus)
Genetic diversity is fundamental to maintaining the long-term viability of populations, yet reduced genetic variation is often associated with small, isolated populations. To examine the relationship between demography and genetic variation, variation at hypervariable loci (e.g., microsatellite DNA loci) is often measured. However, these loci are selectively neutral (or near neutral) and may no...
متن کاملFemale choice and variation in the major histocompatibility complex.
The cause of the high genetic variability in the major histocompatibility complex (MHC) is not entirely clear. Recently, two reports suggest that female mice prefer to mate with males different from them at the MHC. A model of female choice appropriate for those observations is developed here. Female choice can in fact reduce the observed proportions of homozygotes, maintain genetic polymorphis...
متن کاملThe major histocompatibility complex.
The major histocompatibility complex on the sixth chromosome controls expression of a complex series of cell surface antigens which comprise the human leukocyte antigen (HLA) system. These markers, beyond their importance in human organ transplantation, have been demonstrated to occur with an increased prevalence in certain disease states. The group of conditions showing the closest association...
متن کاملRecombination and selection in the major histocompatibility complex of the endangered forest musk deer (Moschus berezovskii).
The forest musk deer (Moschus berezovskii) is a high elevation species distributed across western China and northern Vietnam. Once abundant, habitat loss and poaching has led to a dramatic decrease in population numbers prompting the IUCN to list the species as endangered. Here, we characterized the genetic diversity of a Major Histocompatibility Complex (MHC) locus and teased apart driving fac...
