WebIn 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), or phenotypic (e.g. body size, skin pigmentation). WebAug 19, 2014 · Clinal variation is commonly interpreted as evidence of adaptive differentiation, although clines can also be produced by stochastic forces. ...

WebClinal characters change from one end of the geographic range to another. The extent of this change is reflected in the slope of the cline. 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 … WebCLD is an important part of process development and results in the creation of specific mAb-producing cell lines (or clones). CLD is a multi-step process involving host cell line selection, transfection of the gene of interest (GOI), clonal isolation, selection, amplification, and finally, clonal expansion ( Lee et al., 2024 ).
