Traits and Reproduction

What is the relationship between Genes and Protein Molecules?

• Protein Molecules tell genes what to do

• Genes tell Protein molecules what to do

• Genes and Protein Molecules have nothing to do with each other

• Genes and Protein Molecule fight each other.

Which of the following is an inherited trait?

• being able to roll your tongue

• snapping fingers

• height

• being able to raise one eyebrow

Two parents have brown hair. They have parents that also have brown hair. Their child has red hair. Why might this happen?

• The environment changed their hair color

• The child chose to have red hair instead of brown

• The child has a mutation that gave them red hair

• There is no reason for the child having red hair

There are two wolves that have the same proteins for paw size in their cells. The wolves have different parents. What can you say about the wolves' paw size?

• They will have the same paw size since their proteins for paw size are the same so the proteins will connect in the same way.

• They will have the same paw size since all wolves have the same paw size.

• They will have different paw sizes because even with the same proteins for paw size, the proteins can connect in different ways.

• They will have different paw sizes since only offspring from the same parents have the same size paws.

A dragonfly has blue wings. Its mother has blue wings, but its father has colorless wings. Which of these statements explains why the dragonfly has blue wings?

• The dragonfly inherited one copy of the gene for wing color from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make its wings blue.

• The dragonfly inherited one copy of the gene for wing color from its mother and one copy from its father. Those genes connect together to make its wings blue. 

• The dragonfly inherited its copies of the gene for wing color from its mother and not from its father. Those genes connect together to make its wings blue.

• The dragonfly inherited its copies of the gene for wing color from its mother and not from its father. Just like its mother’s genes, those genes instruct for proteins that connect in ways that make its wings blue.
