What is cloning and how is it considered a type of asexual reproduction?

I’m doing some practice exam questions for biology, and i’m not sure how to do these 3 parts to the question.

Red flowered snapdragons are crossed with white flowered snapdragons, producing all pink snapdragons in the f1 generation. what would you expect if you crossed pink with pink? 3/4, 1/4, 1/2 red, 3/4,/1/2,/1/4 pink,1/2, 3/4, 1/4 white

The kind of fertilization found in the majority of aquatic animals is (internal or external) fertilization.
