Question
Most adaptations that help an organism survive are passed on from parent to child as ___traits?
- Adaptable
- Physical
- More
- Inherited
Hint:
Adaptation passed among generations with meaning same as legacy.
The correct answer is: Inherited
Genetic information of an individual is stored in the form of DNA in most of the organisms. The information is in the form of nucleic acid sequence or genes which are passed from one generation to the next. This is termed as inheritance. Likeliness in traits between a parent and its offspring is due to inheritance.
The genetic inheritance is important to study evolution.
- Genetic information is stored in DNA present in the nucleus of the cells
- Genetic information can be passed from parent to offspring which is termed as inheritance
