🌳 Family Tree Basics — Generations, Notation & Draw-It-Out

Blood Relations is one of the most predictable topics in competitive exams — once you learn to draw a family tree instantly, most questions become trivial. A family tree is drawn across generation levels: Grandparents at the top, then Parents, then the Current generation, then Children at the bottom.

Standard 4-Level TreeGen 0 → Gen 1 → Gen 2 → Gen 3Grandparents → Parents → Current → Children. Always label generations first.
Male / Female NotationSquare = Male, Circle = FemaleIn diagrams: □ for males, ○ for females. Use M/F label when drawing quickly.
Draw-It-Out MethodRead → Assign → Connect → AnswerStep 1: Read each clue. Step 2: Assign a letter/name. Step 3: Draw arrows. Step 4: Trace the path.
Spouse NotationA ══ B (double line)Married couples are connected by a horizontal double line (or = sign in rough work).
Golden Rule: Never assume gender from a name unless stated. Names like Kiran, Rajan, Harpreet are gender-neutral. Always look for explicit clues — "he", "she", "son", "daughter", "brother", "sister".
