Familial Relations

Overview & Fundamental Concept

Exhaustive AISSEE Class 6 Intelligence guide for Familial Relations (Blood Relations). Covers 5-generation family trees, gender notations (square/circle), maternal vs paternal kinships, dialogue and photograph decoding, coded relations, solved models, and 10 drills.

• 1. What is a Family Tree Diagram? A hierarchical graphical representation that maps biological and marital relationships across distinct generational tiers.
• 2. The 5 Generational Tiers:
• • Generation +2 (Grandparents): Grandfather, Grandmother (Paternal and Maternal).
• • Generation +1 (Parents & In-Laws): Father, Mother, Uncle (Paternal Chacha / Maternal Mama), Aunt (Bua / Mausi / Mami / Chachi), Father-in-law, Mother-in-law.
• • Generation 0 (Cadet's Generation / Self): Self, Brother, Sister, Cousin, Brother-in-law, Sister-in-law, Husband, Wife.
• • Generation -1 (Children & Nieces/Nephews): Son, Daughter, Nephew (brother's or sister's son), Niece (brother's or sister's daughter), Son-in-law, Daughter-in-law.
• • Generation -2 (Grandchildren): Grandson, Granddaughter.
• 3. Standard Structural Symbols (Pencil Notation):
• • Male: Enclose within a Square [ $\square$ ] or mark with a plus sign $(+)$.
• • Female: Enclose within a Circle ( $\bigcirc$ ) or mark with a minus sign $(-)$.
• • Married Couple (Spouses): Connect with a Double Horizontal Line ($=$), e.g., $[ ext{Father}] = ( ext{Mother})$.
• • Siblings (Brother-Sister / Brother-Brother): Connect with a Single Horizontal Dash ($-$), e.g., $[ ext{Brother}] - ( ext{Sister})$.
• • Parent-Child Relation: Connect with a Vertical Downward Line ($\downarrow$), placing the parent above and child below.

• 1. Paternal Relations (Father's Family Line):
• • Father's Father: Paternal Grandfather (Dada).
• • Father's Mother: Paternal Grandmother (Dadi).
• • Father's Brother: Paternal Uncle (Chacha / Tau).
• • Father's Sister: Paternal Aunt (Bua / Phupi).
• • Father's Sister's Husband: Paternal Uncle (Fufa).
• • Children of Paternal Uncle/Aunt: Cousins (Paternal cousin brothers/sisters).
• 2. Maternal Relations (Mother's Family Line):
• • Mother's Father: Maternal Grandfather (Nana).
• • Mother's Mother: Maternal Grandmother (Nani).
• • Mother's Brother: Maternal Uncle (Mama).
• • Mother's Brother's Wife: Maternal Aunt (Mami).
• • Mother's Sister: Maternal Aunt (Mausi).
• • Mother's Sister's Husband: Maternal Uncle (Mausa).
• 3. The Crucial 'Only Son' vs 'Only Child' Distinction:
• • 'Only Son': Does NOT mean an only child! A father who has an 'only son' can still have multiple daughters! The son has sisters.
• • 'Only Child': Means the individual has ZERO brothers and ZERO sisters. An only child has no siblings.
• 4. In-Law Kinships:
• • Brother-in-law: Spouse's brother OR Sister's husband.
• • Sister-in-law: Spouse's sister OR Brother's wife.
• • Nephew & Niece: Brother's/Sister's son is Nephew; Brother's/Sister's daughter is Niece.

• 1. What are Photograph / Dialogue Problems? A speaker points to a portrait or person and describes their relationship through a chain of possessive statements (e.g., 'He is the son of the only daughter of my mother.').
• 2. The 3-Step 'Backwards' Substitution Algorithm:
• • Step 1: Identify the Speaker. Locate the possessive anchor 'my' in the statement.
• • Step 2: Trace from the Back (Right-to-Left). Break the sentence at each 'of' and decode backwards one step at a time.
• • Step 3: Replace each phrase with its single-word equivalent.
• • Demonstration: 'He is the [son] of the [only daughter] of [my mother]'.
  1. Anchor: 'My mother' (Speaker's mother).
  2. Backward step: 'Only daughter of my mother' $\implies$ If speaker is female: Herself; If speaker is male: His sister.
  3. Backward step: 'Son of that person' $\implies$ Her son (or sister's son $\implies$ Nephew).
• 3. Instant Dialogue Translation Cheat-Sheet:
• • 'Only son of my father' (Speaker is male) $\implies$ Myself.
• • 'Only son of my father' (Speaker is female) $\implies$ My Brother.
• • 'Only daughter of my mother' (Speaker is female) $\implies$ Myself.
• • 'Only daughter of my mother' (Speaker is male) $\implies$ My Sister.
• • 'Father of my daughter's mother' $\implies$ Daughter's mother is Wife $\implies$ Father of Wife is Father-in-law.
• • 'Brother of my wife' $\implies$ Brother-in-law.

• 1. What are Coded Blood Relations? Relationships are represented using arithmetic or symbolic operators:
  • Example: $P + Q$ means $P$ is the father of $Q$; $P - Q$ means $P$ is the sister of $Q$; $P \times Q$ means $P$ is the brother of $Q$; $P \div Q$ means $P$ is the mother of $Q$.
• 2. Rapid 2-Step Elimination Method:
• • Step 1: Gender Filter. If the target relation requires a specific gender, eliminate options where the person's gender is wrong or unknown.
  Example: If asked to find 'M is the aunt of N', $M$ MUST BE FEMALE. If an option ends with $M$ without any following operator (e.g., $N \times K + M$), $M$'s gender cannot be determined $\implies$ eliminate option immediately!
• • Step 2: Generation Gap Summation ($sum \Delta G$). Assign numerical generation values to operators:
  Father/Mother $= +1$; Brother/Sister $= 0$; Son/Daughter $= -1$.
  If 'Aunt' requires a generation difference of $+1$, calculate the algebraic sum of the path from target to subject. Any option that does not sum to $+1$ is eliminated without drawing!
• 3. Verification by Mini-Tree: Once non-matching options are eliminated by Gender and Generation Gap, sketch a quick 10-second mini-tree for the single remaining candidate to verify.
