Concept:
Living organisms show similarities with their parents because certain characteristics are transferred from parents to offspring. This transmission of traits is one of the most fundamental principles of genetics.
Definition:
\[
\text{Heredity} = \text{Transmission of characters from parents to offspring}
\]
Traits such as eye color, height, skin color, hair type, and blood group are inherited through genes.
Step 1: Understanding the meaning of heredity.
The question asks for the biological term used for the passing of traits from one generation to the next generation.
This biological phenomenon is known as:
\[
\boxed{\text{Heredity}}
\]
Step 2: Analysis of other options.
• Option (1) Inheritance: Although related, heredity is the scientific biological term commonly used for transfer of traits.
• Option (2) Evolution: Evolution refers to gradual changes in organisms over many generations.
• Option (4) Segregation: Segregation refers to separation of alleles during gamete formation according to Mendel's law.
Thus, the correct answer is:
\[
\boxed{(3)\ \text{Heredity}}
\]
