The answer is (3) an increase in the proportion of offspring <span>that have favorable characteristics.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited.

So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.
Therefore, the </span>proportion of offspring <span>that have favorable characteristics in such environment will increase.</span>
<span>There have been studies done that show using this technology to create milk makes the milk more dangerous. People who drink this milk are more likely to get prostate cancer, breast cancer and colon cancer. The technology also creates many toxins that can harm the cows and milk drinkers.</span>
