Unit 7- Traits and Reproduction (Amplify)

a long piece of DNA that contains many genes

• DNA

• chromosome

• feature

• fertilization

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.

Henry is studying a family of tree frogs that have poisonous skin, and he finds one frog with a mutation for the poison feature. Which of these statements about the tree frog with the mutation is true?

• There will be no change to the frog’s poison.

• The frog must be more poisonous than other frogs.

• The frog must be less poisonous than other frogs.

• There must have been a change in the frog’s genes.
