Assessment of Morphogenetic Trait of AEL and CRT in Relation to Hb Genotype

Human genetics are known as hereditary traits, these hereditary traits include the dominant and recessive traits in humans. Most of the genes are transmitted in the Mendelian pattern and a few are transmitted through the non-Mendelian pattern that includes: co-dominance, sex-linked genes and polygenes. The aim of this research is to assess the morphogenetic trait such as attached earlobe (AEL) and tongue rolling (CRT) in relation to Hb genotype. Three hundred and thirty seven (337) subjects comprising of 162 females and 175 males, aged 18-61 years were randomly selected. The ears and ability to roll tongue were studied in the subject and recorded, as well as genotype as revealed by the subject. Prevalence of 57.2% (193) was recorded for the entire population studied as belonging to CRT as against 42.6% (144) belong to cRT. Prevalence for AEL was recorded as 38.2% (129) as against 61.6% (208) for uAEL. AA has the highest prevalence of 73.2% followed by AS with 19.8%, the least was SS 1 (0.3%). Genotype in relation to AEL and CRT recorded only 13% of AA individuals that have AEL and can roll tongue (CRT), while only 2.9% of the AS individuals that have AEL can roll their tongues. One (0.3%) SS individual have AEL and can roll tongue. Relating Hb genotype to AEL and CRT is of great important in the study of forensic pathology and anthropology.
