Reassessing the Evolutionary History of the 17q21 Inversion Polymorphism
Alves, Joao M; Lima, Ana C; Pais, Isa A; Amir, Nadir; Celestino, Ricardo; Piras, Giovanna; Monne, Maria; Comas, David; Heutink, Peter; Chikhi, LounèsA polymorphic inversion that lies on chromosome 17q21 comprises two major haplotype families (H1 and H2) that not only differ in orientation but also in copy-number. Although the processes driving the spread of the inversion-associated lineage (H2) in humans remain unclear, a selective advantage has been proposed for one of its subtypes. Here, we genotyped a large panel of individuals from previously overlooked...

Linkage disequilibrium and haplotype homozygosity in population samples genotyp...
Wang, Hui; Lin, Chia-Ho; Service, Susan; Chen, Yuguo; Freimer, Nelson; Sabatti, Chiara; Karayiorgou, Maria; Roos, J. Louw; Pretorious, HermanObjective: Analyze the information contained in homozygous haplotypes detected with high density genotyping. Methods: We analyze the genotypes of ∼2,500 markers on chr 22 in 12 population samples, each including 200 individuals. We develop a measure of disequilibrium based on haplotype homozygosity and an algorithm to identify genomic segments characterized by non-random homozygosity (NRH), taking into account ...
