In regards to the guppy study in natural ponds, for which pondsdid male guppies have the highest mean number of spots?
Answer
ponds with no predators
ponds with cichlids only
ponds with killifish only
ponds with cichlids and killifish
In regards to the guppy study in natural ponds, for which ponds didmale 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 numberassociated with the
different type of predators?
Answer
There should be no difference in selective pressure fromkillifish versus cichlids.
Cichlids are apparently more dangerous as predators to guppies,and thus can be expected to exert a stronger selective pressureaffecting spot number.
Killifish are the more dangerous predator to guppies and thusthey would be more likely to exert the stronger selectivepressure.
What was the average number of spots at the start of allyour experiments?
2.0
3.0
4.0
5.0
