- X-linked recessive



A) If the father is unaffected (healthy) and the mother is a carrier (no clinical symptoms):

• One daughter out of two will be a carrier
• One son out of two will be G6PD deficient

B) If the father is G6PD deficient and the mother is unaffected:

• All daughters will be carriers
• All sons will be unaffected

C) If the father is G6PD deficient and the mother is a carrier:

• One daughter out of two will be G6PD deficient
• One daughter out of two will be a carrier
• One son out of two will be G6PD deficient
• One son out of two will be unaffected

D) If the father is unaffected and the mother is G6PD deficient:

• All daughters will be carriers
• All sons will be G6PD deficient

E) If both father and mother are G6PD deficient:

• All daughters will be G6PD deficient
• All sons will be G6PD deficient
