<prompt> True statement about inheritance of an X linked recessive trait is50 of boys of carrier mother are affected50 of girls of diseased father arecarrierFather transmits disease to the sonMother transmits the disease to the daughter  <response>: Features of X-linked disordersExcept for a few conditions, all X-linked disorders are X-linked recessive.A male has only one X-chromosome, the male with an affected gene on X-chromosome will always manifest the disease.On the other hand, the female has 2 X-chromosomes, the heterozygous female will be a carrier because of the expression of a normal allele on the other X-chromosome.Note - Female with Turner syndrome only one X chromosome can manifest X-linked recessive disorders.50 boys of the carrier mother will be affected.All daughters of an affected father will become a carrier, i.e. affected father will transmit the defective X-chromosome to all the daughters.Father will not transmit the disease to son as boys do not inherit X-chromosome from father.
