Abstract
Honeybee Apis mellifera adansonii, dominant honey producing species in Nigeria was subjected to genetic variability studies using Simple Sequence Repeat (SSR) in other to provide the baseline data in Nigeria. Nine (9) Simple Sequence Repeats (SSR) primers were used to assess the genetic diversity in Two (2) worker bees each collected from 22 colonies found in the four apiaries in Ijebu environs of Ogun State. Data collected were subjected to analysis and results showed that six (6) out of nine primers produced 80 reproducible, polymorphic bands while the remaining three (3) were monomorphic. Gene diversity (H ) in total population and magnitude of differentiation among T populations (FST) was 0.430 and 0.340, respectively. Analysis of Molecular Variance (AMOVA) partitioned the total genetic variation as 70% within, 30% among populations. The cluster analysis showed that Ipari-Oke 3 and Odo-Epo 1-8 populations diverged from others which showed they are closer in genetic distances while Ipari-Oke 1 and Odo-Epo 2-5 were newly observed subcluster which represents another subspecies. In conclusion, genetic variations existed amongst the honey worker bees populations in Ogun State.
