which allele combination represents a male who has an x - linked recessive disorder?\no x^ry\no x^ry\no…

Brief Explanations:

Males have XY sex - chromosomes. In X - linked recessive disorders, the disorder is carried on the X - chromosome. For a male to have an X - linked recessive disorder, he must have the recessive allele on his single X - chromosome. So the allele combination is (X^rY) where (X^r) is the recessive allele on the X - chromosome and Y is the Y - chromosome.

Answer:

(X^rY) (corresponding to the second option in the multiple - choice list assuming (X^rY) is the second option as (X^rY) is the correct answer for a male with an X - linked recessive disorder)
