Duchenne muscular dystrophy is a genetic disorder that arises from a recessive x-linked allele. why is this disorder almost always restricted to males?

As female has XX chromosome so they can be carrier if one chromosome is recessive to the disease and have muscular distrpphy if female has homozygous condition for the disease !!

But in male ; which has only one X chromosome i.e XY , it can not be a carrier !! Male even if has the recessive gene but due to having only one X gene will get muscular distrophy.

I hope now you understand; if got any problem ; comment !!

The answer is going to be a because ik that i’m right
