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 ...
Genetics is the study of genes, genetic variation, and heredity in organisms. [1] [2] [3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance ...
Somatic cells (of the body) develop afresh in each generation from the germ plasm. August Weismann proposed the germ plasm theory in the 19th century, before the foundation of modern genetics . Germ plasm ( German : Keimplasma ) is a biological concept developed in the 19th century by the German biologist August Weismann .
In terms of genetics, this is called an increase in allele frequency. Alleles become more or less common either by chance in a process called genetic drift or by natural selection . [ 13 ] In natural selection, if an allele makes it more likely for an organism to survive and reproduce, then over time this allele becomes more common.
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
The discovery of DNA as the blueprint for life and breakthroughs in molecular genetics research came from the combined works of many scientists. In 1869, chemist Johann Friedrich Miescher, who was researching the composition of white blood cells, discovered and isolated a new molecule that he named nuclein from the cell nucleus, which would ultimately be the first discovery of the molecule DNA ...
Topics of genetic history of "anatomically modern" humans (Homo sapiens) are under Category:Ancient human genetic history. Subcategories This category has the following 10 subcategories, out of 10 total.
Modern genetics began with the work of the Augustinian friar Gregor Johann Mendel. His works on pea plants, published in 1866, provided the initial evidence that, on its rediscovery in 1900's, helped to establish the theory of Mendelian inheritance .
