DNA analysis, which has proven to be a major advance in the field of paternity testing, involves the direct examination of the genetic material that a child inherited from its biological parents. DNA is located throughout the human body and in the same identical form.
In a plant with a taproot system, the taproot is the largest, most central, and most dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward.
The shape of taproots can vary but the typical shapes include: 1  Conical root: this type of root tuber is conical in shape, i.e. widest at the top and tapering steadily towards the bottom: e.g. carrot. 2  Fusiform root: this root is widest in the middle and tapers towards the top and the bottom: e.g. radish.
