What is the probability that offspring of two heterogeneous parents will be homologous recessive?
Matrixectomy: If your doctor believes the destruction of the nail matrix is necessary after removing the toenail, he or she will perform a partial or full matrixectomy (or matricectomy), which is permanent toenail removal by applying a chemical agent (most commonly phenol or sodium hydroxide) to the matrix.
You can't ignore your toenail falling off. Besides looking ugly, a toenail hanging where it shouldn't can cause a significant amount of pain. When your toenail is falling off medics call it onychoptosis or onycholysis, which means separation of the nail from the nail bed. At first the nail looks discolored and possibly bleeds, then begins to loosen (the toe may also swell) and eventually it separates from the toe and falls off.
