Hi can someone help me with these cladograms? But specifically in the format of the PowerPoint slide below!

Use the information in the following table to construct a cladogram. Characters Lungfish Frogs | Elephant Lizard x Crocodile x Bird x Sea Lion x Lungs Gills in Adults Tetrapod Amniotic Egg X Subdenal Fat Ability to see UV Light Gizzard Feathers Tusks Use the information in the following table to construct a cladogram. Characters Kangaroo Mouse | Human Nerve Cord Legs Nature of Egg Development Frog Turtle IX IX X requires water hard shell develops inside develops inside marsupial develops inside placental in egg in egg | placental Hair Pouch

In this kind of format:

Answer 1
