Genetics: Traits and Behaviors

The video introduces a unit on genetics, covering key vocabulary such as chromosomes, DNA, traits, and offspring. It explains dominant and recessive traits, inherited and learned behaviors, and acquired traits. Students are encouraged to write definitions on index cards and explore examples of each concept. The lesson aims to provide a foundational understanding of genetics and its application in understanding organisms.

What is the purpose of using index cards in this genetics unit?

• To create flashcards for vocabulary words

• To record lab experiment results

• To draw diagrams of genetic processes

• To write essays on genetic topics

What is the role of chromosomes in genetics?

• They help in the digestion of food

• They are responsible for energy production in cells

• They contain information about an organism's characteristics

• They are the building blocks of proteins

Which of the following best describes DNA?
