What is the primary function of a gene?

To provide energy for the body's cells

To act as an instruction for a specific trait

To determine the age of an organism

To store memories from an organism's experiences

For any given trait, where does an offspring get its set of genetic instructions?

They are created new in the offspring and are not from the parents

They receive different combinations of genes from their parents by chance.

One brother inherited genes only from the mother, and the other only from the father.

The total number of genes a family shares

The differences in inherited traits among family members

The process of genes being passed from parents to children

The idea that all children from the same parents are identical

All children inherit the exact same genes from their parents.

Gene combination is random, leading to variation in traits.

Hair texture is determined only by the father's genes.

Children can only inherit traits that both parents display.
