...Albinism Albinism is a congenital disorder where there is a complete or partial absence of pigment in the skin, hair, and eyes because of the absence or defect in the enzyme that produces melanin. Melanin is responsible for pigment in plants, animals, and protists. Albinism in man has been described by many Greek and Roman writers, and the first accurate scientific paper about it was written in 1908 by Sir Archibald Garrod. Most people only think of humans in the case of albinism, but in reality, it affects humans as well as plants and animals. In plants, Albinism is the total or partial absence of chlorophyll. Because there is an inadequate amount of chlorophyll, photosynthesis is impaired. As a result, plants with albinism usually die at a young age. According to scientific authors Maya Kumari, Heather J. Clarke, Ian Small, and Kadambot H. M. Siddique, some environmental conditions like temperature, light, media composition, and culture conditions can play a role in determining the frequency of albino plant formation. Although environmental factors can sometimes play a role, genetic factors are the main determinants. Genetic studies in different crops show that it is a recessive trait governed by many loci. Because nuclear as well as chloroplast genomes affect albinism, incompatibilities between them is a likely cause of pigment defects in hybrid progenies (Kumari). In angiosperms large amounts of these incompatibilities are found. Unfortunately, there is no solution...
