unusual facts about Genetic variation


Butler Act

By the terms of the statute, it could be argued, it was not illegal to teach that apes descended from protozoa, to teach the mechanisms of variation and natural selection, or to teach the prevailing scientific theories of geology or the age of the Earth.


John Speakman

Speakman's group was the first to link genetic variation to differences in food consumption in humans by examining polymorphic variation in the Fat mass and obesity associated (FTO) gene.

Julia Bodmer

The Bodmers jointly founded a new laboratory at the Institute of Molecular Medicine where they worked on genetic variation in human populations.

Genetic architecture

Epistasis: when the alleles at one locus change the phenotypic effects of genetic variation at another locus, the two genes are said to exhibit 'epistasis' in their interactions.

Genetic history of indigenous peoples of the Americas

Prior to the 1952 confirmation of DNA as the hereditary material by Alfred Hershey and Martha Chase, scientists used blood proteins to study human genetic variation.

Genetic studies on Sri Lankan Tamils

Furthermore, a study looking at genetic variation of the FUT2 gene in the Sri Lankan Tamil and Sinhalese population, found similar genetic backgrounds for both ethnic groups, with little genetic flow from other neighbouring Asian population groups.

Maxillary central incisor

Sinodonty, a genetic variation occurring in Native Americans and some East Asian populations, is possibly a trait retained from an indigenous East Asian archaic human ancestor Homo Erectus Pekinensis.

Roslag sheep

Although there is considerable genetic variation in most of the northern European sheep breeds, Roslag sheep, as well as Dala Fur sheep (also originating in Sweden) and Estonian Ruhnu sheep exhibit the highest within-population inbreeding due to declining numbers of the breeds.

Supertaster

The term originates with experimental psychologist Linda Bartoshuk who has spent much of her career studying genetic variation in taste perception.

Viral phylodynamics

Because computing likelihoods for genealogical data under complex simulation models has proven difficult, an alternative statistical approach called Approximate Bayesian Computation (ABC) is becoming popular in fitting these simulation models to patterns of genetic variation, following successful application of this approach to bacterial diseases.

Wilhelm Johannsen

His findings led him to oppose contemporary Darwinists, most notably Francis Galton and Karl Pearson, who held the occurrence of normal distributed trait variation in populations as proof of gradual genetic variation on which selection could act.
