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 ...
Estabrook's eugenic reanalysis strongly emphasized heredity, and he reversed Dugdale's arguments about the environment, proposing controls on reproduction and other eugenics solutions, since he claimed no amount of environmental changes could alter their genetic inheritance towards criminality. [7]
Walter Sutton (left) and Theodor Boveri (right) independently developed different parts of the chromosome theory of inheritance in 1902.. The Boveri–Sutton chromosome theory (also known as the chromosome theory of inheritance or the Sutton–Boveri theory) is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material.
Heredity in Relation to Eugenics is a book by American eugenicist Charles Benedict Davenport, published in 1911. It argued that many human traits were genetically inherited, and that it would therefore be possible to selectively breed people for desirable traits to improve the human race. [ 1 ]
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals.
Genetics [ edit ] As the X chromosome is one of the sex chromosomes (the other being the Y chromosome ), X-linked inheritance is determined by the sex of the parent carrying a specific gene and can often seem complex.
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.
