Those which are best able to survive and reproduce do so, and tend to leave the most offspring. This is called “natural selection.” 4. Over time, if s ...

The number of phenotypes produced for a trait depends on how many genes control the trait. Natural selection on single-gene traits can lead to changes in allele frequencies a ...
