I’m doing a biology lab and am struggling with the subject of selectively neutral alleles.
Two questions I need help with:
What factors control the frequency of selectively neutral alleles?
Could evolution occur if all alleles were selectively neutral? Explain why or why not.

I am doing my biology lab. my lab is about Ecological Niche. bacteria is our model organism. we set temperature and PH as the “space” or niche. finally I get a graph PH vs temperature. part of organism’s environment actually is same. so, I think my results doesn’t prove Gause’s principle. however, I am not sure about my conclusion.
