The Suri/Huacaya phenotype inheritance in alpaca was tested on rwo indipendent Peruvian sources of records: the Registry of Mallkin farm (588 offspring by Suri sire x Suri dam from 62 paternal half sib families, and 2,126 offspring by Huacaya sire x Huacaya dam froom 177 paternal half sib families) and the results of the Quimsachata INIA ILPA Puno experimental trial (two reciprocal experimental test-crosses, involving a total of 17 unrelated males and 149 unrelated females). The data support a genetic model in which two linked loci must simultaneously be homozigous for recessive alleles in order to produce 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 mutation on some germinal lines of Huacaya animals. The direct mutation can be estimated at 0.0014

Abstract

The Suri/Huacaya phenotype inheritance in alpaca was tested on rwo indipendent Peruvian sources of records: the Registry of Mallkin farm (588 offspring by Suri sire x Suri dam from 62 paternal half sib families, and 2,126 offspring by Huacaya sire x Huacaya dam froom 177 paternal half sib families) and the results of the Quimsachata INIA ILPA Puno experimental trial (two reciprocal experimental test-crosses, involving a total of 17 unrelated males and 149 unrelated females). The data support a genetic model in which two linked loci must simultaneously be homozigous for recessive alleles in order to produce 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 mutation on some germinal lines of Huacaya animals. The direct mutation can be estimated at 0.0014
