To solve the problems in blood relation, one should know how to draw a family tree. A family tree is a pictorial representation of genealogical data.

### How to draw a family tree

1. All the female members of the family are represented by a circle. The name of the person is written inside the circle for convenience.
2. All the male members of the family are represented by a square. The name of the person is written inside the square for convenience.
3. The relation between two members of the family is shown by single line.
4. The spouse relation is represented by the two ends of a double-headed arrow.
5. All the family members of the upper generation are represented above in the family tree. Ex: father, mother, uncle, aunt etc. The logic can be extended by representing the grandparents above the parents in the family tree. Ex: grandfather and grandmother.
6. All the family members of the same generation are represented in the middle of the family tree. Ex: brothers, Sisters, cousins, wife, husband, etc.
7. All the family members of the next generation are represented below in the family tree. Ex: Daughter, son, niece, nephew.
