Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Albinism is inherited in an autosomal recessive pattern that means both parents contribute a mutated gene for the person to have albinism. So, there is a $25\%$ chance that any of their children will have albinism. Then $50\%$ of the children will carry the mutated gene, but will not have albinism. The last possibility is to neither have albinism or carry the mutated gene, that's the other $25\%$ chance.
