In Duchenne's Dystrophy, which gender can carry the gene?

Duchenne's Dystrophy is a genetic disorder that is X-linked recessive, meaning that the gene responsible for the condition is located on the X chromosome. Both males and females can carry this gene, but they exhibit different implications for its expression due to their chromosomal differences.

Males have one X and one Y chromosome (XY). If a male inherits an affected X chromosome, he will express Duchenne's Dystrophy because he does not have a second X chromosome that could potentially carry a normal copy of the gene.

Females, on the other hand, have two X chromosomes (XX). If a female has one affected X chromosome, she can still have a normal allele on her other X chromosome, which often results in the female being a carrier without showing symptoms of the disease. Carriers can pass on the affected X chromosome to their offspring.

This genetic understanding illustrates why both genders can carry the gene for Duchenne's Dystrophy, making the correct answer inclusive of both males and females.
