Human genetics includes the study of inheritance in humans. Human genetics is a broad sector that includes various sub-sectors such as cytogenetics, molecular genetics, biochemistry, clinical genetics, and genetic counseling, and others. These sectors help in understanding the concepts of gene structure and organization, expression of the gene, detection of mutation and its analysis, linkage analysis and genetic mapping, and physical mapping among others. The study of human genetics allows us to understand genetically complexes in diseases and epistatic interactions such as ethical, legal, and social issues.
Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
Genes are the common factor of the qualities of most human-inherited traits. The study of human genetics can answer questions about human nature, can help understand diseases and the development of effective disease treatment, and help us to understand the genetics of human life.
Genomics is the field of genetics concerned with structural and functional studies of the genome. A genome is all the DNA contained within an organism or a cell including nuclear and mitochondrial DNA. The human genome is the total collection of genes in a human being contained in the human chromosome, composed of over three billion nucleotides.
Medical genetics is the branch of medicine that involves the diagnosis and management of hereditary disorders. Medical genetics is the application of genetics to medical care. It overlaps human genetics, for example, research on the causes and inheritance of genetic disorders would be considered within both human genetics and medical genetics, while the diagnosis, management, and counseling of individuals with genetic disorders would be considered part of medical genetics.
