Abstract

The relationships between some wool characteristics and blood group genotypes (AaAa, AbAb, AaAC, AAb, AC and AbAc) were studied in Ossimi and Rahmani Egyptian fat-tailed breeds of sheep.

Interrupted medullation and coarse wool percentages and grade of wool were significantly related to blood group genotypes (P < 0·01). Fibre length and diameter and continuous medullation percentage were significantly related to genotype (P < 0·05). Staple length, number of crimps per cm, percentages of kemp, clean wool, impurities, moisture regain and fine wool were not significantly related to blood group genotype (P > 0·05).
