I don’t understand what to do. If you can please explain but just giving the answers would be fine.

1.) heterozygous 2.) hairy 3.) hh 4.) heterozygous 5.) no fur | as for 5, 6, and 7 i need more information because you can't see the guinea pig. number 6 could either be "HH" or "hh" depending on what it looks like, since it's heterozygous. The punnet square on the bottom right goes as follows, (from left to right) HH, Hh, hH, hh.
