Inheritance Inheritance. Metachromatic leukodystrophy is inherited in an autosomal recessive manner. This means that both copies of the disease-causing gene in each cell must have a mutation for an individual to be affected. Individuals inherit two copies of each gene - one copy from each parent.
Crown-of-thorns starfish. Crown-of-thorns starfish are one of the most damaging creatures of tropical coral reefs, particularly Australia's Great Barrier Reef. They are voracious predators that release the contents of their stomach on to the coral.
The body form of the crown-of-thorns starfish is fundamentally the same as that of a typical starfish, with a central disk and radiating arms. Its special traits, however, include being disc-shaped, multiple-armed, flexible, prehensile, and heavily spined, and having a large ratio of stomach surface to body mass.he body form of the crown-of-thorns starfish is fundamentally the same as that of a typical starfish, with a central disk and radiating arms.
