0.25 of their sons is expected to be g6pd.

Because the sons will inherit only one of their mother's two X chromosomes. The father is normal, so he will pass on a normal allele. The mother has an X-linked recessive allele, so she can only pass on that allele to her daughters, who will not have G6PD deficiency.

The sons will have a 50% chance of inheriting the X chromosome from their mother—that is, they'll get either the normal or G6PD-deficient allele from her. If they get the normal allele from her, then they'll be fine and won't be affected by G6PD deficiency. If they get the G6PD-deficient allele from her, then they'll have G6PD deficiency themselves and be affected by it.
