Natural selection is when favorable traits are passed down to offspring while harmful and less favorable traits are eliminated, due to higher predation, competition from the o â¦ rganisms with more favored traits, etc. Since organisms with more favored traits will, logically, have much more chance of surviving to reproduce than those who lack the favored traits, the next generations will slowly start to accumulate a higher percentage of organisms who have the favored traits.
There are four ways I know of that the frequency of alleles in a gene pool can change over time. 1. natural selection-If one organism has an allele that is beneficial to th â¦ e survival of the population it will become selected for and will be mated with.Over time the amount of offspring with this gene/allele will increase while other genes that were not selected for because may decrease.. natural selection-If one organism has an allele that is beneficial to th â¦ e survival of the population it will become selected for and will be mated with.
