dc.description.abstractA study on the distribution and frequencies of coat colour, wattle, beard, horn, and hair type using 375 extensively managed local goats wascarried out in the three administrative zones of Niger state, Nigeria. The animals were scored for coat colour pigmentation pattern, presence orabsence of wattle, beard, horn, hair type and extra teat. The study showed that light brown is the predominant colour in zones A (43.24%) and zone C (47.57%). Dark brown colour was predominant in zone B (37.82%) followed by light brown (31.09%). The observed frequencies for wattle (Waw) and extra teat (Ete) were above (p < 0.01) the expected Mendelian value of 75% for a dominant gene in all the zones (90.34, 86.55, 87.39 percent for wattle and 91.73, 96.64, 98.21, percent for extra teat in zones A, B, and C, respectively). The gene frequency for beard (Brb) were significantly lower (p < 0.01) than the expected Mendelian value of 75% for a dominant gene in zone A (66.20%) and zone B (55.46%), butwas higher in zone C (83.78%). The gene frequency for polledness (Pop) was 0.00% for all the zones. The gene frequency for soft hair.was more than (p < 0.01) the expected Mendelian value of 75% for dominant genes in zone C (87.33%) but fell short in zone A (60.69%) and zone B (43.70%), respectively. It was concluded that coat colour variation exist in local goats reared extensively in Niger state.
