The department of Biology was instituted in 1966 as the third department in the defunct School of Biological Sciences. The other departments were Botany and Zoology. In its early years, the department was responsible for the Preliminary Biology, Medicine and related disciplines, NCE (Biology) and B.Sc. Education Biology programmes. Consequent on a deliberate recruitment of the requisite staff by the department, the senate in 1971/72 approved a B.Sc. (Hons) degree in Biology.

    Effect of Three Common Orange Flavored Drinks on Progeny Counts and Sex Ratio of Drosophila melanogaster Flies
    (Federal University Wukari, 2017-04) Giwa, A.; Adekoya, K.O.; Abanikannda, O.
    Fruit drinks are a perfect fast food for today’s eat on the run lifestyle. In this study, Drosophila melanogaster flies were exposed to three local and common orange flavoured drinks (Nutri-C, Sari-C and Eve). The Drosophila melanogaster flies were fed on a Banana-Garri medium containing the test substances in varying concentrations (1, 2, 5, 10, 25, 50, 100%). The flies were bred in the media in the ratio of a male to three females, left to mate and lay eggs for six days. The numbers of offspring were counted and sex recorded. This was done until no adult eclosionin the media. There was a significant decrease (P<0.0001) in the progeny counts due to the medium and treatment.Also observed was the significant alteration in the sex ratio (P<0.05). Food products containing chemicals shouldbe adequately tested before release into the market.
