The data support a genetic model in which two linked loci must simultaneously be homozygous for recessive alleles in order to produce the Huacaya phenotype. The estimated recombination rate between these loci was 0.099 (95% C.L. = 0.029-0.204). The birth of 3 Suri offspring from Huacaya x Huacaya mating is explained by a new dominant mutation on some germinal lines of Huacaya animals. The direct mutation rate can be estimated at 0.0014.application/pdfenginfo:eu-repo/semantics/restrictedAccessAlpacaHuacayaLinkageSegregation analysisSuriinfo:eu-repo/semantics/bookParthttps://purl.org/pe-repo/ocde/ford#4.04.02
