Explanation:

The complementation test is widely used in genetics for assessing whether two mutations associated with a phenotypic trait represent two different gene variants of the same gene (i.e., two alleles of the same gene) or if they are mutations associated with two different genes. In a recessive trait, the offspring must receive one recessive allele from each parent in order to show the recessive phenotype (in this case, albinism). Moreover, in heterozygous individuals for a trait that exhibits complete dominance, recessive alleles always are masked by dominant alleles. Albinism is a multigenic (polygenic) recessive trait, thereby individuals who carry recessive mutations causing albinism on different genes will have zero probability (none) of having offspring with albinism.
