>>19062759"The gene responsible for earlobe attachment is inherited in a simple dominant pattern. This means that if an individual inherits the gene for attached earlobes from either one of their parents, they are likely to have attached earlobes themselves. The earlobe attachment is a trait that is passed down from generation to generation and can be influenced by many factors such as genetics, ethnicity, and geography.
According to a study conducted on European American, Latin American, and Chinese cohorts, earlobes were classified as free, partially attached, or attached. An individual was considered to possess attached earlobes if at least one ear was rated as attached. It is believed that the attached earlobes are a result of a dominant gene, and it is estimated that approximately 75% of the population has attached earlobes. However, this number can vary depending on the ethnicity of the population being studied. In European populations, attached earlobes are more common and are found in a higher percentage of the population compared to other ethnicities. This may be due to the genetic mixing of different populations within Europe, leading to a greater variety of earlobe shapes and sizes. In contrast, Asian populations, such as the Chinese, have a lower percentage of attached earlobes compared to European populations. This is believed to be due to the fact that Asia has a more homogeneous population, with less genetic mixing from different populations. Latin American populations have a higher percentage of attached earlobes compared to Asian populations, but a lower percentage compared to European populations. This may be due to the genetic mixing of different populations within Latin America, such as indigenous populations, European populations, and African populations ."-ChatBot.
