Abstract
Morphological traits are measurable characteristics of individual organism. These include aspects of the outward appearance (shape, structure, color, and pattern) as well as the form and structure of the internal parts like bones and organs. In this study, the occurrences of these traits among students of University of Ilorin, Ilorin, Nigeria were investigated. Ten (10) traits (Tongue rolling, widow’s peak, chin cleft, dimple, free earlobe, Achoo syndrome, bent little finger, early onset myopia, hand clasping and hair phalanges) were selected and a retrospective study was carried out among 2000 students in nine (9) different faculties. The results were analyzed using Microsoft excel 2010, SPSS-version 21 and Hardy-Weinberg (H-W) equation. The H-W equation showed that the frequencies of recessive alleles (q) were higher than the dominant alleles in all the traits. Also, the homozygous dominant genotypes in all the traits except early onset myopia were less than the homozygous recessive and heterozygous genotypes. This study provides normative data for the distribution of the ten traits among the students of University of Ilorin.
