The importance of family traits is undeniable.

Family traits can be used to:

1. Determine Intelligence:

Intelligence is an important family trait that can be passed on from parent to offspring. Parents’ academic traits can help choose the right career path for a student.

2. Determine or Detect Diseases:

Some certain diseases run in the family. They are inherited by offspring, for example, high blood pressure, short-sightedness, sickle cell anemia, asthma, etc.

Once offspring start showing signs of diseases, like asthma, the doctors’ job is made easy if he knows the family’s disease history.

Sickle cell anemia is another good example. For a child to be affected, both parents must pass the defective form of the gene, and if only one parent passes the sickle cell gene to the child, the child will have the sickle cell trait. A man and a woman with the defective gene are usually advised not to have children.

3. Determine Who a Child Resembles:

When a child resembles one of the parents, it helps prove that he is an offspring of that parent. This is important, especially in paternity cases, mostly when a man is not certain if he is the true father.

4. Determines Blood Group:

Family traits determine the blood group of an individual which could be A, B, AB or O.

5. Helps Trace Family Genealogy:

A family tree, also called a genealogy, is used to represent generations of families and how they are linked throughout the years. It helps individuals know where they came from, or learn about hereditary diseases in their family

A simple family tree.

How to make a family tree:

1. Gather information about your family: It is usually advised to visit an older person of your family who would be able to assist with naming family members from older generations. Speak to as many people as you can including your parents. You might want to find documents, pictures, newspaper clippings, photos, and more to make a more visual family tree.

2. Make an outline with all the family members you want to include, remember you can always keep adding to this! You can start with your great-grandparents.

3. Create a ‘leaf’ for each family member – add names, dates, photos, and any other information you want to include, to each leaf.

4. Distribute to your family or share in the classroom! They would all be impressed!
