What are haplotypes?

Some articles on haplotypes, haplotype:

HLA-A34 - A34-B Haplotypes
... The most prominent of these haplotypes is A34-Cw11(1)-B56 ... This haplotype is found from Western Australia to Taiwan to New Zealand indicating a recent genetic linkage between these peoples ... Another frequently found haplotype is the A34-B61 (A*3401Cw*04B*B4002) haplotype ...
HLA-B48 - Haplotypes
... There is a known haplotype that covers a distance from South America to Siberia and maybe indicative of recent long range migration ... This haplotype is found in Peru, Mexico, Eskimos ... The A-Cw-B component of the haplotype appears to have been conserved, however, equilibration of linkage to DR-DQ is more evident in Asian and Native American populations ...
HLA A1-B8-DR3-DQ2 - Recombination Dynamics
... The average length of these 'haplotypes' are about 1 million nucleotides ... Multigene haplotypes following standard dynamics only exist in robust populations for a short time, the average distance between genes of about 200,000 nts, which means that over ... few individuals that lived in isolation as long as other haplotypes are maintained ...
Mannan-binding Lectin - Structure - Genes and Polymorphisms
... linkage disequilibrium vary among ethnic groups resulting in seven major haplotypes HYPA, LYQA, LYPA, LXPA, LYPB, LYQC and HYPD ... Differences in the distribution of these haplotypes are the major cause of interracial variations in MBL serum levels ... Both HYPA and LYQA are high-producing haplotypes, LYPA intermediate-producing haplotype and LXPA low-producing haplotype, whereas LYPB, LYQC and HYPD are defective haplotypes, which cause ...
HLA-DR9 - Genetic Linkage
... DR09 Haplotypes DRA DRB1 Haplotypes *0101 *0901 *0101 DQA1 DQB1 DRB1 Haplotypes *0301 *0303 *0901 HLA-A HLA-B DRB1 Haplotypes *0000 *0000 *0901 HLA-DR9 is genetically linked to HLA-DR53, and HLA-DQ3 and DQ9 serotypes ...
