HEAMOGLOBIN POLYMORPHISM FROM TWO POPULATIONS OF WEST
AFRICAN DWARF GOAT IN WESTERN NIGERIA

Haemoglobin Polymorphism in West African Dwarf (WAD) goat populations from Oyo and Ogun State was investigated using cellulose acetate electrophoresis system. Five milliliters (5ml) of blood sample were collected through jugular vein into a heparinized bottle from 60 WAD goat, comprising of 30 goats from each population. The
result showed different band of alleles of haemoglobin which were counted and score accordingly, Data generated were analysed using Tool For Population Genetic Analysis (TFPGA) software. The result of the analysis revealed two alleles HbA and HbB controlling three genotypes HbAA, HbAB and HbBB. Frequency ranged between 0.217 and 0.500 for HbA with an average of 0.359 while it ranged from 0.500 to 0.783 for HbB allele with an average of 0.41. Test for Hardy-Weinberg’ Equilibrium was not significant (p < 0.05) for the two populations. Observed and Expected heterozygosity (HO and HE) ranged from 0.333 to 0.435 with an average of 0.384 and from 0.348 to 509 with an average of 0.428. The gene diversity (D) ranged between 0.340 and 5.00 with a mean of 0.470. The Wright F statistic analysis revealed FIT, FST and FIS value as 0.261, 0.138 and 0.148 respectively indicating and inbreeding population with moderate genetic diversity.
