Differences between genotypes: CSV, SV(Saarloss), (NO)GSD
![]() Differences between haplotypes (still rather partial, used only 4 microsatellites on Y chromosome) ![]() Real test use exemple (Weimaraner breed): "Y chromosomal polymorphisms as well as mtDNA sequences were initially investigated to gauge the accuracy of historic stud book information of the current Weimaraner population in Germany. Analysis of Y chromosomal markers revealed that three of nine markers were monomorphic in 34 male Weimaraners. We identified four Y chromosomal haplotypes or patrilineages, with haplotype Y2 being the most frequent (50%) across all Weimaraners (Table 1). Two patrilineages (Y1, Y3) were unique to SH Weimaraners. In addition, three different mtDNA haplotypes or matrilineages were identified, two of these (M1, M2) were only observed in this breed, with haplotype M1 being most frequent (67.7%; Table 1).Haplotype M2 differs from M3 only in a single position (nucleotide 8479) in the ATP synthase subunit 6 gene. This exchange appears to be unique to Weimaraners, as has been underscored by extensive database searches. Concerning the accuracy of old Weimaraner stud book information, we identified inconsistencies in a few matri- and patrilineages where historical records cannot be reconciled with the inferred relationships based on Y and mt haplotype data."
