In regards to the guppy study in natural ponds, for which ponds did male guppies have the lowest mean number of spots?
Answer

ponds with no predators

ponds with cichlids only

ponds with killifish only

ponds with cichlids and killifish
Answer




Can you explain any differences in average spot number associated with the
different type of predators?
Answer

There should be no difference in selective pressure from killifish versus cichlids.

Cichlids are apparently more dangerous as predators to guppies, and thus can be expected to exert a stronger selective pressure affecting spot number.


Killifish are the more dangerous predator to guppies and thus they would be more likely to exert the stronger selective pressure.




What was the average number of spots at the start of all your experiments?
