Which best explains why males cannot be carriers of X-linked traits?

Males only have one X chromosome

Males have two copies of the X chromosome

Males can be heterozygous for a particular trait

Males do not have an X chromosome

17.

Colorblindness is more common in males than in females because......

fathers pass the allele for colorblindness to their sons only

the allele for colorblindness is located on the Y chromosome

the allele for colorblindness is recessive and located on the X chromosome

males who are colorblind have two copies of the allele for colorblindness
