Phenotypic and genetic categorization of qualitative traits in extensively managed local goat (Capra aegagrus) population of Niger State, Nigeria

Abstract

A study on the distribution and frequencies of coat colour, wattle, beard, horn, and hair type using 375 extensively managed local goats was carried out in the three administrative zones of Niger state, Nigeria.
