In males, there is only one X chromosome, and if it carries a recessive allele, that allele will be expressed because there is no corresponding dominant allele on the Y chromosome to mask its expression. Therefore, the Y chromosome not containing the wild-type allele is the reason why recessive alleles in the X chromosome are expressed in males.
