@shrutipande9 Ma'am Would it be ''B''? :P

My guess..lol

shrutipande9 · Answer

so if u hv 1 defective trait in the X chromosome.
then males wud have only 1X so the defective trait has 2 be expressed.
but in females 2X so to express this defective trait both the X need 2 have this. and the chances of having both X carying defective trait is rare as compared to 1 carrrying the defective trait....
