WebThe examination of phenotypic resistance to PI when testing non-B HIV strains often requires classical cell culture proce-dures, which are time-consuming and difficult to perform. Re-combinant virus assays have been optimized for testing phe-notypic resistance in subtype B variants, but performance in testing non-B viruses is not well known.

Abstract Urbanization offers the opportunity to examine the evolutionary effects of natural selection, genetic drift, and gene flow on … In biology, a cline (from the Greek κλίνειν klinein, meaning "to lean") is a measurable gradient in a single characteristic (or biological trait) of a species across its geographical range. First coined by Julian Huxley in 1938, the "character" of the cline referred to is usually genetic (e.g. allele frequency, blood type), … Zobraziť viac Clines are often cited to be the result of two opposing drivers: selection and gene flow (also known as migration). Selection causes adaptation to the local environment, resulting in different genotypes or phenotypes … Zobraziť viac According to Huxley, clines can be classified into two categories; continuous clines and discontinuous stepped clines. These types of clines characterise the way that a genetic or phenotypic trait transforms from one end of its geographical … Zobraziť viac Although the term "cline" was first officially coined by Huxley in 1938, gradients and geographic variations in the character states of species have been observed for centuries. … Zobraziť viac The steepness, or gradient, of a cline reflects the extent of the differentiation in the character across a geographic range. For example, a steep cline could indicate large variation in the colour of plumage between adjacent bird populations. It has been previously … Zobraziť viac It was originally assumed that geographic isolation was a necessary precursor to speciation (allopatric speciation). The possibility that … Zobraziť viac Clines can be portrayed graphically on maps using lines that show the transition in character state from one end of the geographic … Zobraziť viac
