Positive selection creates a hitchhiking valley — reduced diversity and extended haplotype homozygosity (EHH)
Parameters
Sweep width: — kb
Min diversity: —
Max EHH: —
iHS score: —
EHH (Extended Haplotype Homozygosity) measures how far identical haplotypes extend around the selected site. High EHH = long-range LD from rapid hitchhiking.
