Explanation:
The gen for haemophilia has an X-linked recessive pattern, therefore all descendant males for these couple will not inherit the gen, because they will receive the Y from the father and the X from the mother, if the couple have girls, all the female descendants will inherit the recessive gen.
X Y
X XX XY
X XX XY
But in this case they had a boy with the haemophilia gen, meaning that the mother has a recessive gen for haemophilia and in this case, they will have 25% change to give birth to a healthy boy, 25% chance to give birth to a girl with recessive pattern (carrier) and 25% to give birth to a girl with dominant pattern (affected).
X Y
X XX XY
X XX XY
XX (carrier girl)
XY (healthy boy)
XY (affected boy- first child)
XX (affected girl)
