Do all offspring have the same traits as their parents?
No
Yes
If you look more like your mom, then you received more genes from her.
True
False
Two parrots have different parents. One parrot has red chest feathers, and the other parrot has yellow chest feathers. Why do the parrots have different feather colors on their chest?
Each parrot has different feather colors because offspring from different parents will have different feather colors.
Each parrot has different feather colors because they have different versions of the gene for feather color that connect together to make different feather colors.
The parrots have different versions of the gene for feather color, and the genes are different colors in each parrot’s feathers.
The parrots have different versions of the gene for feather color, which instruct for different proteins that connect in different ways to make different feather colors.
A father rabbit had long ears while the mother rabbit had short ears. Which of these statements explains why one of the baby bunnies could have long ears?
The baby bunny inherited its copies of the gene for ear length from its father and not from its mother. Those genes connect together to make its ears long.
The baby bunny inherited its copies of the gene for ear length from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its ears long.
The baby bunny inherited one copy of the gene for ear length from its father and one copy from its mother. That gene combination instructs for proteins that connect in ways that make long ears.
The baby bunny inherited one copy of the gene for ear length from its father and one copy from its mother. Those genes connect together to make its long ears.
In living things, proteins _____ in different ways to perform specific jobs (functions) or to create specific structures.
instruct
connect
construct
copy
Brayden is trying to figure out how petal shape is determined in two different roses. In the pink rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are different from each other. How does this affect how many types of proteins there are in each petal cell?
The pink rose has one type of protein for the petal shape feature. The yellow rose has two types of protein for the petal shape feature.
The pink rose has one type of protein for the petal shape feature. The yellow rose has one type of protein for the petal shape feature.
The pink rose has two types of protein for the petal shape feature. The yellow rose has two types of protein for the petal shape feature.
It is impossible to say anything about proteins from the given information.

Which one is an example of a "trait"?
Red hair
Eye color
Shoe brand
Shape of ear
An instruction for making a protein molecule
Function
Fertilization
Gene
Allele
A specific characteristic of an individual organism
feature
trait
gene
gene version
Any difference in traits between individual organisms
variation
heterozygous
homozygous
The part of the cell where the genes are located
ribosomes
nucleus
mitochondria
An organism produced as a result of reproduction
offspring
mutation
species
Traits, such as your hair or eye color, are determined by the proteins made by ribosomes in your body.
True
False
There are two genes that decide each of your traits, and those two genes are always exactly alike.
True
False
An offspring cannot have a trait if neither of its parents have it.
True
False
Two bears are unrelated but have the same proteins for ear shape. How will their ears compare with each other?
They will have the same ear shape since their proteins are the same and connect in the same way.
They will have the same ear shape since all bears have the same ears.
They will have different ear shapes since only offspring from the same parents have the same ear shape.
A tree frog has a mutation for their poison feature. This means:
there will be no change to the frog's poison
the frog will be more poisonous than the rest of its family
the frog will be less poisonous than the rest of its family
there must have been a change in the frog's genes.
Henry is studying a family of tree frogs that have poisonous skin, and he finds one frog with a mutation for the poison feature. Which of these statements about the tree frog with the mutation is true?
There will be no change to the frog’s poison.
The frog must be more poisonous than other frogs.
The frog must be less poisonous than other frogs.
There must have been a change in the frog’s genes.
Two sharks have different parents. The two sharks have different proteins in their cells for the color on the tip of their fins. What can you say about the color on the tip of the two sharks' fins?
The fins will be the same color since all sharks have the same fin color.
The fins will be the same color because even with different proteins for fin color, the proteins can connect in the same way.
The fins will be different colors since offspring from different parents will have different colored fins.
The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.
The wing cells of dragonflies have proteins that connect together. In one dragonfly, the structure of the proteins in the wing cells changed, but the amount of that type of protein in the cell stayed the same. What happened to the function of that type of protein?
The amount of that type of protein stayed the same, so its function doesn’t change.
The changed protein connects differently, but its function doesn’t change.
The changed protein connects differently, so its function changes.
The changed protein connects the same, but its function changes.
Some humans have naturally curly hair while others have straight hair because
the genes curly in some humans.
the proteins connect in different ways to create curly or straight hair.
all humans have a different set of parents.
their genes construct proteins for curly hair or straight hair.
