Illustrations are also downloadable as PowerPoint slides. These files can be easily copied and pasted into any existing PowerPoint presentation or can serve as a starting point for a new presentation. These slides are designed to provide lecturers with an easy-to-use and convenient source of illustrations for genetic terms and concepts.
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.
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.
Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. [1] The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. [2]
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.
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 ...
Identifying human races in terms of skin colour, at least as one among several physiological characteristics, has been common since antiquity.Such divisions appeared in early modern scholarship, usually dividing humankind into four or five categories, with colour-based labels: red, yellow, black, white, and sometimes brown.
Race is often culturally understood to be rigid categories (Black, White, Pasifika, Asian, etc) in which people can be classified based on biological markers or physical traits such as skin colour or facial features. This rigid definition of race is no longer accepted by scientific communities.
