Human genetics is the study of inheritance as it occurs in human beings.
History. Mendel studied inheritance.maupertius studied albinism and polydactyly. Haemophilia by Otto.
Biochemical and clinical genetics. Garrod 1901 alkaptonuria study showed how genes control synthesis of enzymes and biochemical process. It studies inborn metabolism errors hemoglobin serum proteins.
Immunogenetics point studies relationship between immune system and genetics. Applied in - rheumatoid arthritis, multiple sclerosis, organ transplantation and diabetes
Developmental genetics. Studies how genes control growth and development of organism. Gene expression. nucleus and cytoplasm development. Developmental anomalies due to radiation and mutations. Embryology studies.
Pharmacogenetics. Role of genomes in response to drugs. study both therapeutic and adverse effects. Drug discovery and drug safety.
Population genetics. Genetic differences within and between populations. Studies adaptation speciation population structure. Uses statistics data analysis computation to study population. Big data analysis improved it. Studies evolution, disease frequency in groups debunked racism.
Radiation genetics. Effect of radiation on gym nutrition and their expression. X-ray cosmic electromagnetic effect studied. Used in Japanese nuclear attack studies. Cancer patient study. Nuclear power station workers.
Eco genetics. Interaction of genes and populations to their environment studied. Effect of UV rays causes skin cancer, milk lactose intolerance, alcohol alcoholism, dost silicosis, smoking lungs cancer.
Use advanced techniques like statistics, data analysis, recombinant DNA STR analysis etc.
Applications in gene editing, therapy, counseling are moving fast with new techniques like whisper big data analysis artificial intelligence.
