Acquired vs Inherited Traits in Animals

The video tutorial explores the diversity of animal species, focusing on their classification into vertebrates and invertebrates. It explains the concept of traits, distinguishing between inherited and acquired traits. Inherited traits are passed down through DNA, while acquired traits result from environmental factors. The tutorial provides examples of both types of traits, emphasizing the role of genetics in inherited traits and the influence of external factors on acquired traits.

What is the primary difference between vertebrates and invertebrates?

• Invertebrates have feathers, vertebrates do not.

• Invertebrates have a backbone, vertebrates do not.

• Vertebrates have a backbone, invertebrates do not.

• Vertebrates have an exoskeleton, invertebrates do not.

Which of the following is a characteristic that can be used to identify living organisms?

• The color of the sky

• The presence of hair or feathers

• The ability to speak

• The type of food they eat

What is the role of DNA in inherited traits?

• DNA is only found in plants.

• DNA carries information on how to make specific traits.

• DNA is responsible for the color of an organism's environment.

• DNA determines the diet of an organism.

Which of the following is an example of an inherited trait?

• A dog learning to sit

• A bird's beak shape

• A horse's ability to jump

• A cat's preference for fish

What is an instinct in animals?

• A behavior that changes daily

• A learned behavior

• A behavior that must be taught

• A behavior animals are born with

Which of the following is NOT an example of an acquired trait?

• Muscles developed from exercise

• A bird's ability to fly

• A change in hair color due to dye

• A scar from an injury

How are acquired traits different from inherited traits?

• Acquired traits are present at birth.

• Acquired traits are only found in plants.

• Acquired traits are passed down through DNA.

• Acquired traits are learned during an organism's lifetime.

Which of the following factors can cause acquired traits?

• Dietary habits

• Parental teaching

• Environmental influences

• Genetic inheritance

What is an example of an acquired trait in animals?

• A bird's instinct to migrate

• A dog's learned ability to fetch

• A cat's inherited fur pattern

• A fish's gills for breathing

Why can't acquired traits be passed down to offspring?

• They are too complex to inherit.

• They are only temporary.

• They are not visible traits.

• They are not encoded in DNA.
