Observation of Dominant and Recessive Character in Humans

Abstract

The majority of the information about our close friends and family members is known to us. Therefore, it's a wonderful idea to gather phenotypic data from family and friends to observe dominant and recessive traits. With few exceptions, phenotypic traits are the morphologically apparent traits that are dominant and recessive aspects of phenotypic behavior seen in both males and females. This study discusses a few prevalent and significant phenotypic traits. Curly hair, brown eyes, widow's peak, dimples, hair on fingers, right-handedness, and free ear lobe are a few typical dominant characteristics taken into account in this study. Recessive characteristics include straight hair, blue eyes, absence of widow's peak, absence of dimple, absence of hair on fingers, left-handedness, and attached ear lobe. The study, which included a balanced cohort of twenty people, reveals complex genetic interactions, defies expectations by demonstrating the emergence of recessive traits in the absence of dominant counterparts, supports established theories regarding handedness, hair type, and eye color, provides a nuanced perspective on traits influenced by hormones, emphasizes the need for more research into the genetic basis of dimples, and highlights the dominance of the right-handed gene globally. These findings offer important insights into the complex genetic landscape that influences phenotypic diversity and advocate for additional research using pedigree analysis to understand and treat hereditary illnesses.
