Selection and haplotypes EHH statistics Anders Albrechtsen
Haplotypes Signature of selection • Mutation enters the population • Mutation increases in frequency due to positive selection • Increases LD • Affects the variability • Increases haplotype similarity • Increases differences with other populations in the whole region
Haplotypes EHH - Extended Haplotype Homozygosity What is EHH? Extended haplotype homozygosity (EHH): EHH at distance x from the core region is the probability that two randomly chosen chromosomes carry a tested core haplotype are homozygous at all SNPs for the entire interval from the core region to the distance x .
