What are Family Traits?

These are transmittable characteristics that are passed from one generation to the other.

Examples of transmittable characteristics, in human beings, are skin colour, height, blood group, body form, the shape of the nose, etc.

Offsprings may possess similar traits from both parents or have different traits. Examples of different traits are when both parents are light-skinned, but the children are dark-skinned.

Examples of transmittable characteristics, in plants, are the height of plants, types of seeds, colour of leaves and flowers, size of fruits, etc. 

Other examples of transmittable/inheritable characteristics, in humans, are intelligence, albinism, baldness, tongue rolling, hemophilia, sickle cell anemia, etc.

Albinism is a group of inherited disorders, where there is little or no production of the pigment, melanin. The type and amount of melanin, your body produces, determines the colour of your skin, hair, and eyes.
