What is Human Genetics? Briefly elucidate different branches of Human Genetics.

 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 can be the common factor of the qualities of most human-inherited traits. Study of human genetics can be useful as it can answer questions about human nature, understand the diseases and development of effective disease treatment, and understand genetics of human life.

Branches of genetics: 

Molecular genetics: 

Molecular genetics is an interdisciplinary sub-branch of genetics dealing with the study of the structure and function of DNA as well as genes (at a molecular level) using techniques such as Polymerase chain reaction and DNA sequencing. 

 Any of the molecular genetic experiments are divided into the 4 sub-steps: 

Separation of molecule 

Purification of molecules 

Processing of molecule

Detection of molecule

Cytogenetics: 

Cytogenetics is a sub-branch of genetics including the study of inheritance through chromosomal analysis utilizing techniques such as karyotyping, chromosomal staining and chromosomal banding, and FISH. Structural and numerical chromosomal abnormalities can be screened using cytogenetic techniques.

However, copy number variations more than 10Kb can only be detected using FISH or DNA microarray. Some of the structural and numerical anomalies ____ _________ _________ ________ _______ ___ _______ ____ __________.
