How is the inheritance of the mother divided between a son and a daughter—is it equally, or is it "to the male, the equivalent of the portion of two females"?

If the mother dies and leaves only two children (a male and a female), the inheritance is divided such that the male receives double the share of the female. So, the male takes two-thirds of the estate, and the female takes one-third. However, if there are other heirs, they take their share first, and then the remainder is divided between the male and female in the same proportion. One should not rush to inquire about inheritance until death occurs.
