1. Introduction
Alpacas have two distinct types of fleeces (Bustinza
Choque, 2001). Huacaya is the most common, has crimped
fibers and a blocky staple, and is similar to wool from Corriedale
sheep. The suri fleece type is less common, and
is highly lustrous with little crimp and distinct locks that
hang limply in a pencil-lock staple. Suri fleeces are somewhat
similar to luster longwool sheep fleeces as typical of
Wensleydale, Teeswater, or Leicester Longwool sheep.
Previous reports of a single dominant gene being
responsible for the suri fleece indicate that genetic control
of fleece type is relatively simple in alpacas, involving
few genes (Ponzoni et al., 2003; Renieri et al., 2009). Experiences
of North American alpaca breeders indicated that
a single-gene hypothesis was not adequate to explain the
differences between these fleece two types in the North
American alpaca population, and were further evaluated
to determine the underlying genetic mechanisms between
these two fleece types.
