This study aimed to evaluate frequency of attached earlobes (dominant) and unattached earlobes (recessive) traits in humans of different age groups. This study was conducted in the Department of Molecular Biology and Genetics of Shaheed Benazir Bhutto University, Shaheed Benazir Abad from September to October 2020. A total of 200 families with attached and unattached earlobes were included by using non-probability convenient sampling. Data was collected regarding attached and unattached earlobes of different people. The data was collected and analysed by using SPSS version 21.0. Results of the study suggested that unattached earlobes were dominant feature, and the attached earlobe feature appears to be recessive among all 200 families. We observed that the dominant feature of the unattached earlobe was more common in the 1 to 20 years’ age group, while the recessive feature of the attached earlobe was common in 31 to 45 years old age group. The study concluded that unattached earlobes can be observed in people of every age group and associated with family traits.
