HELP BIOLOGY ITS IMPORTANT

Wild Type (brown), Chinchilla, Himalayan, Albino

I could be totally off but based on the research I've gathered and my knowledge on genes, that's from most common to least common.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
