The fixation index (F ST) is a measure of population differentiation due to genetic structure. It is frequently estimated from genetic polymorphism data, such as single-nucleotide polymorphisms (SNP) or microsatellites. Developed as a special case of Wright's F-statistics, it is one of the most commonly used statistics in population genetics ...
In quantitative genetics, Q ST is a statistic intended to measure the degree of genetic differentiation among populations with regard to a quantitative trait. It was developed by Ken Spitze in 1993. [1] Its name reflects that Q ST was intended to be analogous to the fixation index for a single genetic locus (F ST).
F IT is the inbreeding coefficient of an individual (I) relative to the total (T) population, as above; F IS is the inbreeding coefficient of an individual (I) relative to the subpopulation (S), using the above for subpopulations and averaging them; and F ST is the effect of subpopulations (S) compared to the total population (T), and is ...
MLST is highly unambiguous and portable. Materials required for ST determination can be exchanged between laboratories. Primer sequences and protocols can be accessed electronically. It is reproducible and scalable. MLST is automated, combines advances in high throughput sequencing and bioinformatics with established population genetics techniques.
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 exact cause of Alzheimer’s disease has long evaded scientists, but experts typically suggest there are likely several factors (like genetics, environment, and lifestyle) that contribute to ...
Steatopygia, a genetic phenotype [5] leading to increased accumulation of adipose tissue in the buttock region, is most notably (but not solely) found among the Khoisan of Southern Africa. It has also been observed among Pygmies of Central Africa and also the Andamanese people, such as the Onge tribe in the Andaman Islands. This genetic ...
Medical genetics X-linked ichthyosis (abbreviated XLI ) is a skin condition caused by the hereditary deficiency of the steroid sulfatase (STS) enzyme that affects 1 in 2000 to 1 in 6000 males. [ 2 ]
