Traits & Reproduction Review Quiz

Lixmarie and Karma are not related. BUT, they both have the same proteins for the trait of eye color in their cells. Which of the following would be true about Lixmarie and Karma?

• They will have the same eye color because they have the same proteins for eye color.

• They will have different eye color because they are not related.

• They will have different eye color because even though the proteins are the same, they can result in different traits.

Two orca whales have different black and white color patterns. They have different color patterns because...

• they are not related to each other so they must have different color patterns.

• they have different genes that connect together to make different color patterns.

• they have different genes which instruct for different proteins that connect in ways to make different color patterns

Two spiders have different parents, but they have the same proteins in their cells for the feature of silk stickiness. Which of the following is true about the spiders' silk stickiness?

• They will have the same silk stickiness because all spiders have the same silk stickiness.

• They will have the same silk stickiness since their proteins for silk stickiness are the same.

• They will have different silk stickiness because even with the same proteins, they could connect in different ways.

• They will have different silk stickiness since only offspring from the same parents can have the same silk stickiness.

What is a mutation?

• A random change to a gene that sometimes results in a new trait.

• A new trait that gets passed down from parents to offspring.

• A copy a gene version that is found in a cell.

How are reproductive cells (egg & sperm) different than other cells in your body?

• Most cells have 2 copies of each gene, but reproductive cells only have 1.

• Most cells have only 1 copy of each gene, but reproductive cells have 2.

• Most cells are small, but reproductive cells are large.

• Most cells are from your mother, but reproductive cells are from your father.

A baby sloth has long arms. Its mother has long arms, but its father had short arms. Which statement explains why the sloth has long arms?

• The sloth inherited one copy of the gene for arm length from each parent. This gene combination gives instructions for proteins that make the sloth have long arms.

• The sloth inherited one copy of the gene for arm length from each parent. These genes connect together in ways that make the sloth have long arms.

• The sloth inherited its gene for arm length from its mother, not from its father. This gene gives instructions for proteins that make the sloth have long arms.

There is a species of lizard (that Mrs. Whitman made up) that can have three different skin colors: green, orange or purple. There are three different types of proteins that can be found in the skin cells of this lizard. The proteins connect to pigment molecules (color molecules) = that give the lizard its trait for color. Click the image to make it bigger. What kind of protein do you think Mrs. Whitman will find in the skin cells of a GREEN lizard?

• protein A

• protein B

• protein C

What color would expect a lizard to be if it had only protein C in its cells?

• Green

• Orange

• Purple

Which of the following is true about proteins?

• Proteins are all the same shape.

• Proteins are only found in our food.

• Proteins are molecules that do important jobs in our cells/bodies

• Proteins get broken down into glucose molecules to make energy for our cells
