VARIATION AND FACTORS THAT CAUSE VARIATION

BY THE END OF THE LESSON :

A student is able to :

• State what variation is

• List variation in humans

• Identify factors that cause

THE MEANING OF VARIATION

The diffrences among individuals of the same

species.

The students are differ :

• Height• Weight• Hair type• Skin colour

There are 2 factors thatcaused variation.

• Genetic Factors

• Environmental Factors

GENETIC FACTORS

1. Genetic factors are inherited.

2. The examples of variations caused

by the genetic factors are :

Types of blood

Colour of eyes

Colour of hair

Types of ear lobes

Types of hair

Pattern of thumb print

Ability to roll the tongue

ENVIROMENTAL FACTORS

1. Environmental factors are

not inherited.

2. The examples of variations caused

by the environmental factors are :

Expose to excessive sunlight

Before joining After joining

The skin colour of the boy has changed. He is tanned.
