SS and ss. Since 100% of the offspring are spotted, then it would need to be SS so that it dominates over all. :)
The stars that is very dim and red is called Red Dwarfs.
Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestor of both these groups was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth. Hope I’ve helped ;)
