Mgbanwe niile, na-eduga na mgbanwe na mmepụta melanin n'ime ahụ. Offọdụ n'ime ndị a jikọtara ya na ịba ụba nke ọrịa kansa  .                                                                

The chance of offspring with albinism resulting from the pairing of an organism with albinism and one without albinism is low. However, because organisms (including humans) can be carriers of genes for albinism without exhibiting any traits, albinistic offspring can be produced by two non-albinistic parents. Albinism usually occurs with equal frequency in both sexes. An exception to this is ocular albinism, which it is passed on to offspring through X-linked inheritance. Thus, ocular albinism occurs more frequently in males as they have a single X and Y chromosome, unlike females, whose genetics are characterized by two X&nbsp;chromosomes.
