Logical Representation

Let:

• $(-)$ denote Female

• $(+)$ denote Male

• $\downarrow$ denote a Generational Shift (Parent to Child)

• $\leftrightarrow$ denote a Sibling relationship

1. First Relationship (Generation 1 to 2):

$A$ is the mother of $B$.

2. Second Relationship (Same Generation):

$B$ is the sister of $C$.

Since $A$ is the mother of $B$, and $B$ and $C$ are siblings, $A$ is also the mother of $C$.

3. Third Relationship (Generation 2 to 3):

$C$ is the father of $D$.

Logical Deduction

Now we trace the path from $A$ to $D$:

• $A$ is the mother of $C$.

• $C$ is the father of $D$.

Therefore, the relationship is defined by the parent of a parent:

Final Conclusion

In the family hierarchy:
