The Role of Genetic in Sex Orientation Preference

Purpose: The aim of the study is to examine the role of genetic in sex orientation preference. Methodology: This study adopted a desktop methodology. This study used secondary data from which include review of existing literature from already published studies and reports that was easily accessed through online journals and libraries. Findings: The study found that genetic markers and variations related to hormone regulation and neural development have been identified as potential contributors, indicating a genetic influence on sexual orientation. Epigenetic factors such as modifications in gene expression, may also be involved in shaping sexual orientation. However, it is important to note that genetics alone cannot fully determine sexual orientation, as it is influenced by a combination of genetic, biological, hormonal, and environmental factors. Unique Contribution to Theory, Practice and Policy: The study was anchored on evolutionary theory of sexual orientation proposed by and epigenetic theory of sexual orientation propounded by Dr. William Rice, an evolutionary biologist. The study recommended the integration of genetic knowledge into therapeutic practices can help reduce stigma and promote self-acceptance among individuals with diverse sexual orientations. It is also crucial to promote policies that protect the rights and well-being of individuals with diverse sexual orientations and address discrimination and prejudice.
