Traits and Reproduction Test Review

Traits and Reproduction Test Review

Let's review our key concepts

Key Concepts for Chapter 1

Multiple Select

Click all that are traits:

• eye color

• 10 fingers

• hair color

• connected ear lobes

Multiple Select

Which are features of snakes? (Select all)

• scale patterns colors

• having scales

Multiple Choice

True or False: The structure of a protein molecule determines its function (how it works).

• True

• False

Multiple Choice

Knowing that proteins connect differently to make traits, if I have 2 dogs with the same type of proteins for eye color, what can you say about their eye color?

• I'm not sure. I don't have enough information.

• The dogs will have the same eye color.

• The dogs will have different eye color.

Chapter 2 Key Concepts

Fill in the Blank

An organism's traits depend on the _____________ in its cells.

Fill in the Blank

___________ give the instructions to the proteins.

Multiple Choice

2. Two goldfish have different parents. One fish has a split tail and the other does not. Why do the goldfish have tails with different shapes?

• They did not get genes from both parents.

• They received different gene versions from their parents.

• The received genes from only one parent.

Fill in the Blank

In a mutation the ___________ version changes and gives the proteins different instructions.

Multiple Choice

How many copies of each gene does each person have?

• 0

• 1

• 2

• 4

Genes

Each parent randomly passes on one of its two copies of each gene to its offspring. Each offspring, therefore, receives two copies of each gene, one from each parent.

Multiple Choice

If the pair of genes are the same version they produce only one type of protein. They are called

• homozygous

• heterozygous

Multiple Choice

If an organism has two different gene versions they produce

two types of proteins. They are called

• heterozygous

• homozygous

Multiple Select

Through sexual reproduction, each offspring can inherit a different combination of gene versions. What does inherit mean? check all that are correct

• passed down

• when offspring get genes from a parent

• to buy

• to borrow

Multiple Choice

Can siblings can have different traits from each other and even from their parents?

• yes

• No

Multiple Choice

Why can siblings can have different traits from each other and even from their parents?

• Boys get their genes from their dads and girls get their genes from their moms.

• Genes are like the lottery. You can get a few genes from your mom and a lot from your dad. It just depends.

• Children (offspring) get half of their genes from their mom and half from their dad- so there are LOTS of combinations.
