Traits & Reproduction Q3 Final

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.

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 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.

 There are two tree frogs that have different proteins in their cells for tongue length. They have different parents. What can you say about the frogs' tongue lengths?

• They will have the same tongue lengths because even with different proteins for tongue length, the proteins can connect in the same way.

• They will have different tongue lengths since offspring from different parents will have different tongue lengths.

• They will have different tongue lengths since their proteins for tongue length are different so the proteins will connect in different ways.

• They will have the same tongue lengths since all tree frogs have the same tongue length.

Two rhinoceros beetles have different parents. They have differently shaped horns. Why do the beetles have differently shaped horns?

• The beetles have different versions of the gene for horn shape, which instruct for different proteins that connect in different ways make their horn shapes different.

• The beetles have different versions of the gene for horn shape. The genes are curved differently in each beetle’s horns.

• Each beetle has a different horn shape because offspring from different parents will have different horn shapes.

• Each beetle has a different horn shape because they have different versions of the gene for horn shape that connect together to make different horn shapes.

 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.

Two mice have different parents. They both have the same proteins for whisker thickness in their cells. What can you say about the mice's whisker thicknesses?

• They will have the same whisker thicknesses since all mice have the same whisker thickness.

• They will have the same whisker thicknesses since their proteins for whisker thickness are the same so the proteins will connect in the same way.

• They will have different whisker thicknesses because even with the same proteins for whisker thickness, the proteins can connect in different ways.

• They will have different whisker thicknesses since only offspring from the same parents have the same whisker thickness.

Two dogs have different parents. One dog has blue eyes, and the other dog has brown eyes. Why do the dogs have different eye colors?

• Each dog has a different eye color because offspring from different parents will have different eye colors.

• Each dog has a different eye color because they have different versions of the gene for eye color that connect together to make different eye colors.

• The dogs have different versions of the gene for eye color, which instruct for different proteins that connect in different ways to make different eye colors.

• The dogs have different versions of the gene for eye color. The genes are different colors for each dog’s eyes.

A shark pup has a pointed fin. Its mother also had a pointed fin, but its father had a rounded fin. Which of these statements explains why the shark pup has a pointed fin?

• The shark pup inherited one copy of the gene for fin shape from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make its fin pointed.

• The shark pup inherited one copy of the gene for fin shape from its mother and one copy from its father. Those genes connect together to make its fin pointed.

• The shark pup inherited its copies of the gene for fin shape from its mother and not from its father. Those genes connect together to make its fin pointed.

• The shark pup inherited its copies of the gene for fin shape 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 fin pointed.

• They will have the same beak thicknesses since all parakeets have the same beak thickness.

• They will have the same beak thicknesses because even with different proteins for beak thickness, the proteins can connect in the same way.

• They will have different beak thicknesses since offspring from different parents will have different beak thicknesses.

• They will have different beak thicknesses since their proteins for beak thickness are different so the proteins will connect in different ways.
