Genetic Part of DMD

The allele for this disease is located in the X chromosome

This disease is most likely to be inherited by males rather than females, because for the male if the allele is present in X chromosome he is affected, but girls have to have the allele present in each X chromosome.

Its is most like like that the boy has a 50, 50 change of be affected with a the disease or not and girls have a 50 ,50 change of either caring the disease or not accruing it.

This disease is a sex-linked recessive disease ,because some of the girls carry this allele as recessive and later can be brought by her and his children
