D Correct answer
Explanation

Holandric genes are located exclusively on the Y chromosome and are transmitted directly from father to son. Unlike sex-linked genes on the X chromosome, these Y-specific genes have no homologous counterpart. Options A, B, and C are incorrect: mutagenes induce mutations, sex-linked genes reside on X chromosomes, and allosomal genes refer to all sex chromosomes generally.
