Contributions to Knowledge

My contribution in the area of genetics has focused majorly on conservation and population genetics. My research findings so far has provided information on the genetic diversities and population structure of fishes in Southwestern rivers and reservoirs which has implications for their conservation and sustainable yield. Paper (i) provided information on the morphological and genetic variation of Tilapia zillii from three reservoirs in Osun state. These findings can be applied in utilization and management of the genetic resources of T. zillii species. In Paper (ii) the effect of toxicants on the genetic diversity of fish populations was determined. The result stresses the need to control the introduction of toxicants into our water bodies as the availability of toxicants in high concentration could substantially reduce genetic diversity in natural populations.

In Paper (iii) and (iv), morphometric and meristic data were used to further establish the morphological differences that exist between populations of a single species of fish collected from different water bodies. These differences which are environmentally induced overtime could result to formation of mophotypes, which could eventually lead to evolution of new species.

In paper (v), histopathological alterations in fish organs were used to determine the effect of toxicants on Sarotherodon galilaeus populations sampled from Opa and Igun reservoirs in Osun State, Nigeria. The result showed that S. galilaeus samples from Igun reservoir were polluted and unfit for human consumption. In Paper (vi), chromosomal studies were carried out on samples of male and female African Pygmy hedgehog, Atelerix albiventris for the purpose of cytogenetic characterization and validation with the only existing report.
