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.

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 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 parakeets have different parents. They each have different proteins in their cells for beak thickness. What can you say about the parakeets' beak thicknesses?

• 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.

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.

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 to 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.

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.

 Two cats have different parents. One cat has stiff fur, and the other cat has soft fur. Why do the cats have different fur softness?

• The cats have different versions of the gene for fur softness. The genes are softer in the fur of one of the cats.

• The cats have different versions of the gene for fur softness, which instruct for different proteins that connect in different ways to make different kinds of fur.

• Each cat has different fur softness because offspring from different parents will have different fur softness.

• Each cat has different traits for fur softness because they have different versions of the gene for fur softness that connect together to make different kinds of fur.
