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 live in two different environments. 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 the environment caused each parrot’s genes to connect differently.

• Each parrot has different feather colors because the environment caused each parrot’s proteins to change the color of its genes.

• 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 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 make its wings blue.

• The dragonfly inherited one copy of the gene for wing color from its mother and one copy from its father. It must have lived in the same environment as its mother, which resulted in its blue wings.

• 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 make its wings blue.

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

• They will have the same tongue lengths since tongue length is only determined by what environment the frogs were raised in.

• 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 will fit together in different ways to determine tongue length.

• They will have the same tongue lengths since they both have proteins for tongue length.

Two rhinoceros beetles were raised in different environments. They have differently shaped pincers. Why do the beetles have differently shaped pincers?

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

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

• Each beetle has a different pincer shape because the environment caused each beetle’s proteins to change the curve of its genes.

• Each beetle has a different pincer shape because the environment caused each beetle’s genes to connect differently.

A father rabbit had long ears while a 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 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 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. It must have lived in the same environment as its father, which resulted in its long ears.

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

• They will have the same whisker thicknesses since all mice have the same whisker thickness even if they were raised in different environments.
• They will have the same whisker thicknesses since their proteins fit together in the same ways to determine whisker thickness.
• They will have different whisker thicknesses since different environments will always cause the proteins to fit together differently.
• They will have different whisker thicknesses since only offspring from the same parents have the same whisker thickness.

Two dogs have the same parents but are raised in different environments. One dog has blue eyes, and the other dog has brown eyes. How is it possible that these dogs have different eye colors?

• Each dog has a different eye color because the environment caused each dog’s genes to connect differently.

• Each dog has a different eye color because the environment caused each dog’s proteins to change the color of its genes.

• The dogs have different versions of the gene for eye color, which instruct for different proteins that 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 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. It must have lived in the same environment as its mother, which resulted in its pointed fin.

• 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 make its fin pointed.

Two parakeets were raised in the same environment by different parents. They both have different proteins in their cells for beak thickness. What can you say about their beak thicknesses?

• They will have the same beak thicknesses since they both have proteins for beak thickness.

• They will have the same beak thicknesses since beak thickness is only determined by what environment the parakeets were raised in.

• 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 will fit together in different ways to determine beak thickness.
