The statement that best explains the mechanisms of inheritance pattern of gene "The allele for blue is an X-linked dominant allele because there are no blue male offspring in second cross."
The mechanism for inheritance of gene:
It is the condition, in which the mutation in an allele, cause the effect in the relevant phenotype.
Similar inheritance pattern is also be seen when the mutated allele will produce new type of the protein which will cause deleterious effect on the normal function of the cell.
Therefore, the best explanation for the mechanisms of inheritance of gene is "The allele for blue color is an X-linked dominant allele because there are no blue male offspring in second cross."
