Science Test 2 Review (Inheritance and Traits)

Front

What is an organism?

Back

An organism is a living entity that can function independently, such as plants, animals, fungi, and microorganisms.

Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for inherited traits passed down from parents to offspring.

Front

True or False: All organisms have the same traits.

Back

False. Organisms can have different traits, which can vary widely even within the same species.

Front

What is a trait?

Back

A trait is a characteristic or feature of an organism, which can be inherited or acquired.

Front

Give an example of an inherited trait in humans.

Back

Examples of inherited traits in humans include eye color, hair color, and certain genetic disorders.

Front

What is the difference between inherited traits and acquired traits?

Back

Inherited traits are passed down from parents to offspring through genes, while acquired traits are developed through environmental influences and experiences.

Front

Which two organisms are more closely related: a cat and a dog, or a cat and a lion?

Back

A cat and a lion are more closely related because they share a more recent common ancestor.

Front

What is the significance of studying traits in organisms?

Back

Studying traits helps scientists understand genetics, evolution, and how species adapt to their environments.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an organism, representing the specific alleles inherited from its parents.
