The allele responsible for a new disease is found only on the X chromosome and is recessive. What does this
suggest about the disease?
The disease is likely to occur equally as often in both men and women.
The disease can only be transmitted to women.
Men are more likely to have the disease than women.
The disease can only be transmitted to men.



Answer :

Final answer:

X-linked recessive diseases affect males more frequently due to their inheritance of a single X chromosome. Females need two copies of the recessive allele to express the trait.


Explanation:

X-linked recessive (XR):

In X-linked recessive inheritance, the gene responsible for the disease is located on the X-chromosome and is recessive. This means that males are more frequently affected by X-linked recessive diseases because they have only one X chromosome, while females need to inherit two copies of the recessive allele to express the trait. Examples of X-linked recessive disorders include red-green color blindness and hemophilia.
