Hint: Most babies are born healthy, but a congenital disorder occurs when a baby is born with a condition that is present from birth. Congenital disorders can be inherited or caused by environmental factors, with varying degrees of impact on a child's health and development.
Complete answer:
Albinism is a condition in which an animal, plant, or person is born without any pigmentation or coloration, resulting in white hair, feathers, scales, and skin, as well as pink eyes in mammals, birds, reptiles, amphibians, and fish, as well as invertebrates. Written reports of albinistic animals can be difficult to verify due to the various uses and interpretations of the terms.
Albinism can reduce an animal's survivability; for example, it's been suggested that albino alligators have a 24-hour average survival span due to their lack of UV protection and lack of camouflage to avoid predators. It's a common misconception that all albino animals have pink or red eyes (due to a lack of pigment in the iris allowing the blood vessels of the retina to be visible), however, this is not the case for some forms of albinism.
Albinism is caused by a lack of melanin pigment in the body. The enzyme tyrosinase is required for melanin biosynthesis. Tyrosinase is a protein that catalyzes the formation of melanin from the amino acid tyrosine.
Thus, Albinism is a congenital disorder resulting from the lack of tyrosinase enzyme.
Note:
Albinism in plants is defined by the loss of chlorophyll pigments and the incomplete differentiation of chloroplast membranes. Plants with albinism have trouble with photosynthesis, which can make them less able to survive. [8] White flowers or other parts of some plant varieties are possible. These plants, however, do not lack chlorophyll entirely. Terms associated with this phenomenon are "hypothermia" and "albiflora".
