A woman has X-linked condition on one of her X chromosomes. These chromosomes can be inherited by:
Only grandchildren
Only sons
Only daughters
Both sons and daughters
Solution
The woman is the carrier of X-linked condition, and she can transmit the carrier allele to both her son and daughter, The resulting son will become diseased because X-linked disorder always affect males due to the presence of single X-chromosome.
The daughter offspring will become a carrier but not diseased because females are affected by X-linked disorder in homozygous recessive condition, i.e. two recessive alleles are required.
