The Tanoli (Hindko/Urdu: تنولی، تناولی) are a Hindkowan tribe living mainly in the Hazara area of Khyber Pakhtunkhwa, Pakistan. [1] [2] They form the majority of the population of Lassan Nawab union council. [3] The Tanoli describe themselves as Barlas Turks. They never submitted to the British colonial rule in the 1840s.
Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. [2] The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy .
The storage, transfer, and expression of genetic information in biological organisms, [14] as manifested by the passing on of phenotypic traits from parents to their offspring, either through sexual or asexual reproduction. Offspring cells or organisms are said to inherit the genetic information of their parents. heritability 1.
The genetic information stored in DNA represents the genotype, whereas the phenotype results from the "interpretation" of that information. Such phenotypes are often displayed by the synthesis of proteins that control the organism's structure and development, or that act as enzymes catalyzing specific metabolic pathways.
Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
Genetic heterogeneity occurs through the production of single or similar phenotypes through different genetic mechanisms. There are two types of genetic heterogeneity: allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; and locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci.
The genetic information is held within genes, and the complete assemblage in an organism is called its genotype. [75] DNA replication is a semiconservative process whereby each strand serves as a template for a new strand of DNA. [72] Mutations are heritable changes in DNA. [72]
