What does natural selection act on, and what does it change?
What does natural selection act on, and what does it change?
Acts on phenotypes, changes genotypes
Why is genetic diversity crucial for species survival?
Why is genetic diversity crucial for species survival?
Increases chance of advantageous alleles
Are there universally 'good' or 'bad' alleles in natural selection?
Are there universally 'good' or 'bad' alleles in natural selection?
No, advantageous alleles depend on env.
