Written Definitions: Each glossary entry has a written definition that has been reviewed for clarity and accuracy by teams of science educators and genetic researchers. All of the definitions were written by the same Ph.D.-level science writer for consistency and accuracy. Illustrations:
In biological taxonomy, race is an informal rank in the taxonomic hierarchy for which various definitions exist. Sometimes it is used to denote a level below that of subspecies, while at other times it is used as a synonym for subspecies. [1] It has been used as a higher rank than strain, with several strains making up one race.
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct , and that using it as a proxy for genetic differences among populations is misleading.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Saini followed up on this idea with her 2019 book Superior: The Return of Race Science. [147] One such post-World War II scientific racism researcher is Arthur Jensen. His most prominent work is The g Factor: The Science of Mental Ability in which he supports the theory that black people are inherently less intelligent than whites.
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.
Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes.
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 ...
