ABSTRACT

A population’s genotypic frequencies and allelic distribution can be studied using Hardy- Weinberg’s equilibrium. This research was done to assess the allelic and genotopic frequencies of post-graduate students at Yogi Vemana University in Kadapa, Andhra Pradesh, India for 15 qualitative morphogenetic traits. This study involved 440 students in total and the frequency order of the blood group was O>B>A>AB in the whole sampled population as well as in both male and female students. In the entire population, Rh-positive (96.1%) was more noticeable than Rh-negative (3.9%). Tongue rolling ability was higher in males (82.02%) than females (59.9%). Tongue folding ability was also higher in both females (89.3%) and males (87.6%). Polydactyly was absent in 94.7% of the sampled population. The prevalence of singlejointed Hitchhiker’s thumb was in 67.3% of the tested population. The absence of a bent little finger was in 83.4% of the sample compared to a straight little finger. The presence of curved hairline was observed in window’s peak 55% more than the widow’s peak (45%). The occurrence of a round chin was more prevalent (79.3%) than a cleft chin and higher in females (82.6%) than males (77.09%). The absence of dimples on the cheeks (81.5%) was more prevalent in the population. The presence of mid-phalangeal hair was more in males (66%) than females (58%). The expression of free earlobe (80.7%), right arm crossing over left arm (85.5%), right-handedness (95.4%) and arched foot (87.5%) was more common in the whole population. In the whole population and male population, all the traits were significant while only the dimpled cheeks in female population were non-significant i.e., only alleles for dimpled cheeks were in equilibrium in the female population and follow the Mendelian ratio in the population of students.

Key words : Allelic frequency, Hardy-Weinberg equilibrium, Morphogenetic traits; Autosomal inheritance.
