Consider the following statements: Statement I: Mitochondrial DNA (mtDNA) generally evolves independently of nuclear chromosomes and is primarily inherited maternally in most animals. Statement II: In haplodiploid (HD) sex determination systems, males are haploid and therefore lack a second copy of nuclear genes that could mask deleterious mutations. Statement III: The absence of masking of nuclear mutations in haploid males can indirectly accelerate the evolution of mitochondrial genes that interact with nuclear-encoded proteins. Which one of the following is correct in respect of the above statements?

Which specific gene located on the sex chromosomes is heavily associated with determining the average height differences observed between human males and females?
