Directional, Diversifying or Stabilizing selection?
Hello Biologists!!!
Would you be so kind as to explain the following...
During warm, dry weather large beetles had a greater number of offspring, while during cold, wet weather, small beetles had more offspring. is this an example of directional selection, diversifying selection, or stabilizing selection?
I would have to guess that it was diversifying selection as two unique types of beetles were forming. CAN ANYONE ADD TO THIS...

i would say stabilizing, as it would probably result in a "medium sized" beetle species. because they would get bigger in summer and smaller in weather. Get my point?

Re: Directional, Diversifying or Stabilizing selection?
Since we're dealing with seasonal weather patterns, it does seem to suggest that over a few years' time, both sizes are favored; a diverse population has the best longterm survival potential, so I'd say you're right here.
