In normal humans, this technique visualizes a set of 46 genetic structures.
Carle and Olson developed an "electrophoretic" version of this technique that involved orthogonal field alternation. Though it has nothing to do with clinical trials, another form of this technique has "3+3", "2+3", and "3+2" types, where the second number indicates the number of haptene-labeled probes. Visualization methods in this technique include the "trypsin-Giemsa", or "G-banding", technique. Cells used in this technique must be treated with colchicine so that they can be arrested in metaphase. In normal humans, this technique visualizes a set of 46 genetic structures. For 10 points, identify this technique used during pregnancies to screen for fetuses having chromosomal abnormalities, which produces an ordered plot of an individual's chromosomes.
