What will be the effect of adding a concentrated urea solution to a protein

Ans.

Albinism shows a genetic disorder, which is characterized by absence of coloration or pigmentation in individuals. It is an autosomal recessive disorder that transmits from parents to their offspring, when offspring receives both the mutated copies of gene responsible for albinism.

For a genetic disorder, dominant or wild type allele is represented by capital letter, such as 'A', while recessive or mutated allele is represented by small letter, 'a'. As 4th picture is representing male and female gametes with recessive alleles (a) , the resulting zygote will have both recessive alleles for albinism (aa), '4th zygote will develop into an albino child.'
