In this test, vlues of most quntittive vriles onsiere were signifintly ifferent (P<0.05) etween istrits. For exmple, the vlue of Wilks Lm ws 0.39 n 0.8 for the femle n mle smple sheep popultions, respetively. This shows tht most (61% for femle n 7% for mle) of the vriility in the isrimintor vriles ws ue to ifferenes etween popultions rther thn vrition within popultions. CONCLUSION Mjority of the sheep in the stuy re hve plin rown ot olor pttern. Generlly, positive n signifint (P<0.05) orreltions were oserve etween oy weight n most of the oy mesurements.

All squre Mhlnois istnes otine mong istrits popultions for femles n mles were signifint (P<0.05), initing the existene of mesurle ifferenes etween femles n mles istrit popultions or istrits.
