    The statement that best explains the mechanisms of inheritance of gene "The allele for blue is an X-linked dominant allele because there are no blue male offspring in cross 2."

    Explanation:

    The mechanism for inheritance of gene is the condition, in which the mutation when happens in one allele and cause the effect in the relevant phenotype. Similar inheritance will also be seen when the mutated allele will produce new type of the protein which will have deletorious effect on the normal function of the cell. In case of the single gene, autosomal dominant, autosomal recessive, X-linked dominant, X - linked recessive and mitochondrial are modes of inheritance.
