Example Questions

Example Question #4 : Inheritance Of Traits

What is an organism? Example: Some organisms are enormous, while others are tiny.

Possible Answers:

A house or building

A type of recreational vehicle

An individual plant, animal, or living thing

Parts of the body with functions to keep humans alive

Correct answer:

An individual plant, animal, or living thing

Explanation:

An organism is a plant, animal, or living thing. Each organism has its traits or characteristics. A trait is a quality or feature that can be used to describe something. Each organism inherits genes from their parents, which determine the mix of traits they receive.

Example Question #1 : Explain Variations Of Traits In Groups Of Organisms

Nevin's cats recently had kittens. The father is black and white while the mother has orange and white stripes. The kittens are a variation of black, white, orange, spots, and stripes. Why is there such a difference in all of the kitten's appearances?

Possible Answers:

It is entirely random, and no one knows what any kitten might look like.

Kittens never look like their parents.

The kittens are a mix of the traits and characteristics of both parents.

The kittens are not the offspring of Nevin's cats.

Correct answer:

The kittens are a mix of the traits and characteristics of both parents.

Explanation:

Nevin's cats look different because there is a variation in their genes and traits. The kittens each inherit half of their genes from each parent, so they are a mix of the two. No two organisms have identical DNA, so they will not look exactly like their mother or their father, but rather a combination of the two.

Example Question #1 : Describe Plant And Animal Inherited Traits

What is the difference between inherited and learned traits?

Possible Answers:

Both inherited traits and learned traits come from parents. Learned characteristics came from the mother, and inherited traits come from the father.

Learned traits are passed down through genes from the parents to offspring. Inherited traits are behaviors that have to be taught.

Inherited traits are passed down to offspring from parents through their genes. Learned traits are taught to the offspring.

There is no difference between inherited and learned traits. They both mean the same thing.

Correct answer:

Inherited traits are passed down to offspring from parents through their genes. Learned traits are taught to the offspring.

Explanation:

Inherited and learned traits are different. Learned characteristics are things taught to an offspring by the parents. Hunting, creating tunnels, and caring for young are all behaviors that are taught through observation and repetition. These are things that need to be learned. Inherited traits are things that are genetic and with an animal from birth. Both of their parents pass these traits to them, and they become a mix of their parents. Hair color, eye color, fur patterns are all examples of inherited traits.

Example Question #12 : Inheritance Of Traits

Which answer choice describes the inherited traits of a puppy?

Possible Answers:

The puppy is large and likes to wrestle with his siblings.

The puppy has a hard time listening to the commands that his owner is teaching him.

The puppy has the same fur color and pattern as its mother and the same eyes as its father.

The puppy has learned to sit, stay, shake, and speak. He gets a treat when he does it right.

Correct answer:

The puppy has the same fur color and pattern as its mother and the same eyes as its father.

Explanation:

Inherited traits come from the parents of a young plant or animal. These are traits that are passed along through genes and are a mix of both the mother and father. The statement that describes this puppies' inherited traits is "The puppy has the same fur color and pattern as its mother and the same eyes as its father.". Fur color, pattern, and eye color all are inherited from the parents of an animal. These are not things he has learned or likes to do; these are traits that he was born with.

Example Question #1 : Describe Plant And Animal Inherited Traits

What traits will a baby sunflower inherit from its parent plants?

Sunflower, Sunflower Field, Yellow

Possible Answers:

Fur color, patterns, teeth shape, ear height, and paw shape.

Flower color, flower position, seed color, seed shape, and leaf pattern.

A baby sunflower will not inherit anything from its parent plants.

There is not enough information to tell what plants will inherit from their parents.

Correct answer:

Flower color, flower position, seed color, seed shape, and leaf pattern.

Explanation:

Plants inherit traits from their parents that give them their characteristics and appearance. A baby sunflower will grow up to look similar to its parents. They will have similar fower colors, flower positions, seed colors, seed shapes, and leaf patterns. When the plant is young, it may look smaller and immature but will grow to have the same features.

Example Question #3 : Describe Plant And Animal Inherited Traits

What is an inherited trait that a rabbit may get from their parents?

Possible Answers:

Favorite food

Fur color

Hobbies

Tricks

Correct answer:

Fur color

Explanation:

An inherited trait that a rabbit might receive from its parents is the color of its fur. Tricks would be a learned straight, something that has to be taught, and hobbies or favorite foods are personal preferences. The color of its fur would be passed down from the parents to offspring.

Example Question #11 : Inheritance Of Traits

These kittens are siblings. How can someone tell they are related?

Cute, Cats, Kittens, Animals, Mammals

Possible Answers:

No one could tell they are related.

They have similar traits and appearances.

They all look the same age.

They are sitting together and close.

Correct answer:

They have similar traits and appearances.

Explanation:

When looking at the kittens in the photo, someone could tell they are related because they have many of the same traits. The kittens have the same body shape, similar eye colors, and shape, and their fur is in the same color range. The two kittens on the ends also seem to have very faint stripes. These traits have been passed down from their parents, so they are probably similar looking adult cats.

Example Question #1 : Describe Plant And Animal Inherited Traits

Which example(s) is a learned behavior rather than an inherited trait?

Possible Answers:

Flower Color

Leaf Pattern

Fur Length

Speaking English

Correct answer:

Speaking English

Explanation:

Inherited traits come from the parents of a young plant or animal. These are traits that are passed along through genes and are a mix of both the mother and father. Learned behaviors are things taught to an offspring by the parents. Hunting, creating tunnels, and caring for young are all behaviors that are taught through observation and repetition. These are things that need to be learned. The color of flower petals, length of animal fur, and patterns on a leaf are all inherited traits. Speaking any language is a learned behavior that must be taught.

Example Question #1 : Describe Plant And Animal Inherited Traits

The picture below is a kitten and its father. What physical traits did the kitten inherit from its parent?

Cat, Cat Mother, Kitten, Striped, Red

Possible Answers:

Fur Pattern

Fur Length

All of the answer choices are correct

Fur color

Correct answer:

All of the answer choices are correct

Explanation:

This kitten and his father look very similar. The kitten has inherited his father's fur color, fur length, and the fur pattern. Offspring receive half of their genetic makeup from each parent and are a mix of the two when born. This kitten has a strong resemblance to his father, and inherited physical traits are the reason for this.

Example Question #51 : 3rd Grade Science

What is an inherited trait?

Possible Answers:

Inherited traits are physical or behavioral traits that are taught to offspring by their parents.

Inherited traits are behavioral traits that offspring pick up on through observation and repetition.

Inherited traits are physical traits that parents pass down to their offspring when the time is right.

Inherited traits are physical or behavioral traits passed down to offspring from parents through their genes.

Correct answer:

Inherited traits are physical or behavioral traits passed down to offspring from parents through their genes.

Explanation:

Inherited traits are things that are genetic and with an animal from birth. Both of their parents pass these traits to them, and they become a mix of their parents. Hair color, eye color, fur patterns are all examples of physical inherited traits. Behavioral inherited traits can include aspects of personality, learning style, vigilance, and desire to hunt.
