You will need the alleged father (your ex-husband) to test along with your sisterâs older son in order to determine paternity through a DNA paternity test. If you would like to determine siblingship, you can take a sibling test (testing your daughter and your sisterâs older son).
The Advantages of the Fibrous Root & Taproot Systems. Fibrous roots branch from the plant's base, and taproots go straight down. Unseen and buried beneath the soil, plant roots perform functions that are necessary to a plant's life. The roots collect water and nutrients for the plant and secure it to the soil. Two basic types of root systems exist. One type is the taproot, which grows vertically and has lateral branches. The other type has fibrous, branching roots that make a network close to the soil surface. Some plants have either a taproot or fibrous roots, and other plants combine the two systems.
A dandelion taproot (left) with the plant (right) The edible, orange part of the carrot is its taproot. A taproot is a large, central, and 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. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as an edible plant, for which its storage capacity has been exaggerated by selection for size and palatability. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example Welwitschia.
