Human genetics
Human genetics is the study of inheritance as it occurs in human beings. It includes the study of human genetic disorders, the work on the human genome, and genetic counselling.
Genes are a common factor behind most inherited traits. Study of human genetics may answer questions about human nature, and the genetics of human life. It helps us to understand the diseases we get, and helps the development of effective disease treatment.

Micrographic karyogram of a human male, showing 46 chromosomes including XY sex chromosomes
Schematic karyogram of a human, with annotated bands and sub-bands. It shows dark and white regions on G banding. It shows 22 homologous chromosomes, both the male (XY) and female (XX) versions of the sex chromosome (bottom right), as well as the mitochondrial genome (at bottom left).
Detail of a human metaphase spread. A region in the pseudoautosomal region of the short arms of the X- and Y-chromosome (PAR1) was detected by fluorescence in situ hybridizaton (green). Chromosomes counterstained in red.
