One hundred and sixty-three (163) Sahelian goats, comprising of 64 males and 99 females aged between 1-5 years, were randomly sampled from populations of Sahelian goats at different locations in Katsina state.  Traits observed included; coat colour pattern, beard (Be), horn (HoL) and wattle (Wa). Goats were scored for these phenotypic variants in the locations. Gene frequencies were calculated using the Hardy–Weinberg equilibrium and the Mendelian principles of inheritance. The dominant genes for beard (Be+) and wattle (Wa+) were found to segregate at low frequencies (0.278 and 0.128 respectively), this frequency was lower than the expected Mendelian ratio of 3:1. Dominant genes for horn (HoL+), however, segregated at high frequency (0.843). Majority of the goat population sampled (61.96%) possessed solid white coat colour while 38.04% had double coat colour patterns, indicative of high level of purity in terms of coat colour, therefore there is need to develop conservation strategies for the goat population in the study area.
