The phylogenetic tree below depicts the relationship among a group of mammals called ungulates and an outgroup. The name “ungulate” means “hoofed animal” as ungulates typically have hoofs on their feet and all descended from a common ancestor with hoofs. Use this information and the phylogenetic tree to answer the following three questions. The trait for hoofed feet is best represented by which letter? [Letter1]. The most recent common ancestor between camel and cow is represented by which letter? [Letter2]

Taxol, extracted from the Pacific Yew tree, is a common chemotherapy drug. Taxol binds to microtubules and stabilizes them, preventing their breakdown and thus preventing the completion of cell division. Cells treated with Taxol will be arrested in which stage of mitosis? [blank1] Which cell cycle checkpoint will these cells not be able to pass? [blank2]
