how much can guppies jump?

I have a 45 gallon fish tank with about 20 guppies and about 7-8 sunset platys, I have about 15 females and 5 males. One day I noticed that some males are constantly chasing one particular female guppy. Is she the best looking one or what? Then another strange thing out of so many females two male guppies one with yellow tail and the other with orange tail and the one with orange tail is chasing the other male thinking that he is female. I am confused now? Then I tried to separate the so called good looking females into one of the baby fish holders that you can keep inside of the main tank, and I know that I took one female and the male with yellow tail put them together, the female has dark black tail and just wanted to see if they will get along with each other, and sure enough they act like they are totally different fish types. No one chases anyone. Then in the other half I know that I had two females. The next day I see only one female out of the two. I started to ask myself If I am crazy I am not seeing it right. So today I see one female guppy that was kind of hiding alone under couple of rocks and decided to give her some rest with the other female in a baby tank. Two hrs. later she is not there, so I wonder how hi can they jump? I looked around the tank hoping to find dried fish but no luck. She is somewhere hiding again. So tree questions: 1. how hi can guppies jump? 2. Out of 10 females why is everybody chasing one particular female? 3. What about male chasing male, what's up with that?
