Example Questions
Example Question #1 : Inheritance Of Traits
What is a trait? Example: A unique trait of the giraffe is its long neck.
Swapping goods in order to get something
A measure of intelligence
A like or dislike of a plant or animal
A quality or characteristic of something
A quality or characteristic of something
A trait is a quality or characteristic that can be used to describe something. In the example provided, a unique trait of the giraffe is its long neck. This characteristic is specific to a giraffe and can be used to describe its appearance. Often the word trait is also heard in English Language Arts when describing a character trait from a story or text.
Example Question #1 : Inheritance Of Traits
Why are there differences in siblings if they have the same parents?
Oldest siblings always get the same traits as their mothers.
Different genes and traits are inherited from the parents.
Most siblings look and act the same; there are few differences.
It is entirely random, and no one knows what any child might look like.
Different genes and traits are inherited from the parents.
When siblings are born, they have different genetic make-ups and inherit different traits from their parents. One child might be born with red hair like the mother and another with brown hair like their father. They may both be tall like their father and have the same shaped eyes like their mother. There will be similarities between the offspring, but no two will be exactly alike because of the differences in the genes they inherit.
Example Question #2 : Inheritance Of Traits
The gorillas in the picture look very similar, but there is a difference in their hair color.
Why would the baby gorilla look slightly different than one of its parents?
The baby is a mix of the traits and characteristics of both parents.
This is not the gorilla's baby; it is just watching it for a friend.
Gorillas never look like their mothers. They only look like their fathers.
The adult gorilla is in the sun, and the baby is in the shade, so they look different.
The baby is a mix of the traits and characteristics of both parents.
The baby gorilla looks different and has darker hair than the parent because it is a mix of both parents' genes and traits. The mother may have more brown/red hair while the father has very dark hair to the baby takes more after the father. Every child born is a mix of their two parents, some genes and traits from each will be instilled in the baby. As plants and animals grow older, they also change in appearance and may start to look like one parent more than the other.
Example Question #3 : Inheritance Of Traits
There are variations of inherited traits that exist in groups of similar organisms because they have different inherited information.
True
False
True
The statement presented is accurate and true. There are variations or differences in the traits of animals, even within the same groups and families. Each offspring inherits different information from their parents, so there are slight differences between them all.
Example Question #4 : Inheritance Of Traits
Plants and animals do not have traits inherited from their parents.
True
False
False
This statement is false and untrue. Plants and animals inherit their traits and genes from their parents. Each offspring is a mix of both parents and will display characteristics from their mother and father. No two plants or animals are precisely the same because they each have unique traits.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
Why does the puppy in the photo below look so similar to both of its parents?
The puppy does not look similar to the adult dogs.
The puppy is a clone of the adult dogs.
The parent's traits have been passed to the puppy.
The adult dogs are not the puppy's parents; they are siblings.
The parent's traits have been passed to the puppy.
Plants and animals inherit their traits and genes from their parents. Each offspring is a mix of both parents and will display characteristics from their mother and father. The adult dogs are all the same species, color, patterns, and breed, so they will pass on traits that will cause the puppy to look similar.
Example Question #3 : Inheritance Of Traits
Why does the kitten in the photo below look different from its mother?
It is a mix of both the mother and father's traits.
The kitten is dirty, and you cannot tell its colors.
That cat is not its mother.
Kittens never look like their mother, only their father.
It is a mix of both the mother and father's traits.
The kitten looks different from the parent because it is a mix of both parents' genes and traits. The mother has orange, white, and brown fur while the kitten only has orange and white. It is possible the father was more orange than other colors, and these genes were the strongest. Every child born is a mix of their two parents, some genes and traits from each will be instilled in the baby. As plants and animals grow older, they also change in appearance and may start to look like one parent more than the other.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
DJ and Johar are brothers, but they don't look alike! How can they be brothers but have variations in their appearance?
Children inherit about 75% of their genes from their mother and 25% from their fathers, so they have a mix of traits.
Each child inherits different genes from their parents, in a 50:50 ratio, so they have a mix of traits.
Youngest siblings always get the same traits as their mothers.
Male siblings always look like their father.
Each child inherits different genes from their parents, in a 50:50 ratio, so they have a mix of traits.
When siblings are born, they have different genetic make-ups and inherit different traits from their parents. One child might be born with red hair like the mother and another with brown hair like their father. They may both be tall like their father and have the same shaped eyes like their mother. There will be similarities between the offspring, but no two will be exactly alike because of the differences in the genes they inherit.
Example Question #4 : Inheritance Of Traits
What is an organism? Example: Some organisms are enormous, while others are tiny.
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
An individual plant, animal, or living thing
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 : Inheritance Of Traits
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?
It is entirely random, and no one knows what any kitten might look like.
The kittens are a mix of the traits and characteristics of both parents.
The kittens are not the offspring of Nevin's cats.
Kittens never look like their parents.
The kittens are a mix of the traits and characteristics of both parents.
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.
