Let's call the colour alleles C for dominant purple, and c for recessive white.
We have crossed Cc with Cc.  So if we put that in a Punnett square, we'd have a CC, two Cc and a cc.  That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)
        
             
        
        
        
1. I’m not really sure how to answer it, i think it’s parasitic 
2. The tick is the parasite since the human is the host 
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)
