It is approached in a multidisciplinary manner from the diverse fields of genetics such as classical, molecular and biochemical genetics, cytogenetics, developmental genetics, etc. The study of human genetics is vital to the understanding of human diseases and development of effective treatments. Besides these, it also presents valuable insights into human nature and personality. The concepts of autosomal dominant and recessive inheritance, X-linked and Y-linked inheritance are vital to this field. Pedigree chart analysis allows the determination of the parent who contributes to the transmission of a specific trait.
