Genetic variation in the ovine KAP22-1 gene and its effect on wool traits in Egyptian sheep.

ABSTRACT: The objective of this study was to investigate the genetic polymorphisms in the keratin-associated protein (KAP22-1) gene in Barki ( n=206 ), Rahmani ( n=28 ) and Ossimi ( n=28 ) as the three major sheep breeds in Egypt. Subsequently, the detected variants were correlated with important wool traits. The traits included greasy fleece weight (GFW, g), staple length (SL, cm), prickle factor (PF, %), medullated fiber (MF, %), fiber diameter (FD, µ m), crimp percentage (CR, %) and the standard deviation of FD (SD fd , µ m), as well as the subjectively assessed traits of kemp score (KS), handle grade (HG), greasy color grade (GCG), bulk grade (BG), luster grade (LG) and staple structure (SST). Animals were genotyped by polymerase chain reaction (PCR) - single strand conformation polymorph
