dc.description.abstract	Morphogenetic traits are observable characters inherited by individuals from their parents in an autosomal dominant or recessive manner and expressed differently among populations. The main objective of the study is to quantify the distribution pattern of human morphogenetic traits and blood group in Chandba secondary and preparatory school students. A descriptive cross sectional study was used to investigate the frequency distribution of six human morphogenetic traits and blood groups and their association among Chandba secondary and preparatory school students. Study participants were selected by stratified sampling technique among the populations. Data from the six morphogenetic traits was gathered through physical observation and examination of individual students. A blood sample was collected from every voluntary student by the finger-prick method and slide agglutination methods of anti-A, anti B and anti-D reagents were used for blood type determination. Morphogenetic traits and blood group data were entered and analyzed using SPSS version 26 statistical software. Descriptive statistics were used to describe the studied characteristics. A chi-square test was used to determine the association between blood groups and morphogenetic traits between male and female students. An association between variables was considered statistically significant if p- value is equal to or less than 0.05. Tongue rolling was expressed as dominant in both male and female individuals. The study indicated that among the morphogenetic traits assessed in the selected population, a significant association was observed between morphogenetic traits of tongue rolling, earlobes, shape of thumb, facial dimples, mid digital hair and handedness with sex in the selected population. In the current study the pattern of distribution of the ABO blood groups was O > A > B > AB. Individuals with the rhesus positive phenotype were more common than those who were rhesus negative. The outcome of this study could be used as baseline information for the effective management of a blood bank inventory in the area. The study of morphogenetic trait is very significant in the area of forensic and anthropological research. For future investigations, data with a larger sample size is recommended to establish the distribution of these traits; it can give additional information regarding the morphological variations, evolution and taxonomic investigation.
