Genetics is the field of science that focuses on
the study of heredity and variation.
Heredity refers to the transmission of traits or
characteristics from one generation to the next.
Variation refers to the differences in traits
between parents and offspring.

Heredity refers to the transmission of traits or

Variation refers to the differences in traits

Heredity and Variation
Types of Variations: Variations can be categorized
into two main types:
 Variation
1.Somatic Variation:
Occurs in the body cells.
Not inherited or transmitted
to the next generation.
Also known as acquired
traits.
Examples include tail
cutting in dogs and piercing
of the pinna (outer ear).
2.Gametic Variation:
Occurs in the gametes or
reproductive cells.
Inherited and transmitted
to offspring.
Also known as inherited
traits.
Examples include human
height and skin color.

Heredity involves the passing of traits from
parents to offspring.
Genes, which are functional units of
heredity, carry these traits.
Genes are short segments of DNA that
encode specific proteins or RNA.
Genetics, a branch of biology, is the study of
genes, heredity, and variations.

Heredity
Heredity Process:
Heredity is the mechanism
through which an organism's
features are passed from one
generation to the next.
Genes play a crucial role in
defining an organism's traits.
