I think the correct answer from the choices listed above is the last option. <span>The relationship in which each codon determines each specific amino acid used for making a protein is considered the Genetic Code. Hope this answers the question. Have a nice day.</span>

Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.
To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.
