Half-blood means sharing one parent but not both: same father, different mothers. Section 3(c) defines it precisely as descent from a common ancestor through different wives. Full-blood (3(b)) = same ancestor, same wife. Uterine blood (3(d)) = same ancestress, different husbands.

1. 1 Pick up HMA 1955.
2. 2 Go to Section 3 — Definitions.
3. 3 Read clause (c): 'two persons are said to be related to each other by half-blood when they are descended from a common ancestor but by different wives.'

The text reads: Section 3(c): Half-blood = descended from common ancestor but by different wives.
