Step 1
I'll solve this population genetics problem step by step, focusing on how fitness impacts allele frequencies.

Step 2
: Understanding Allele Frequency and Fitness

Allele frequency represents the proportion of a specific allele in a population. Fitness describes an allele's ability to contribute to subsequent generations through reproductive success.

Final Answer

Fitness changes allele frequencies by systematically favoring genotypes with higher reproductive success, gradually shifting population genetic composition through natural selection.
