Abstract
Morphological traits are a structural characteristic of an organism that is determined genetically and transmitted from parent to offspring. Some of these characteristics, such as tongue rolling, widow's peak hairline, bent little finger, and ear lobe attachment, are thought to be exact epitome of simple dominant and recessive patterns of transmission; as a demonstration of how Mendelian genetics works, they are clear, and easy to follow epitomes. Thus, these traits were little to No study conducted and documented in Ethiopian population. So, this study has its own contribution to asses and documents the data for next studies as reference. The general objective of this study was to investigate the distribution and frequencies of the morphological traits of tongue rolling, earlobe attachment, widow’s peak, Hitch-hiker’s thumb, Bent little finger and long palmar muscles pattern among Students of Dagmawi Berhan primary school in 2020/2021 academic year. Morphological traits of grade 7 and 8 students of both sexes who volunteered were taken from each participant after agreement or consent was obtained from the students and their respective parents, indicating their readiness to participate. Data collection for morphological traits was done utilizing an observation and recording technique. Figures, tables, and words were used to present the findings. In this study the frequency distribution of the curved widow’s peak was lower than straight hairlines among the population. There were also the more frequency distribution present long Palmaris muscle was found to be male 106 (36%) and lower distribution in female 83 (29%). The study showed that among the morphogenetic traits assessed with the selected population, a significant association was observed in morphogenetic traits of Widow’s peak; tongue rolling, Earlobe attachment and Palmaris longues muscle with sex in the selected population. Other morphogenetic traits which were bent little finger and hitchhiker thumbs did not show association with either of the sex in the study.
