The relatively high percentage of individuals in parts of Africa who are heterozygous for the sickle cell trait is an example of founder effect natural selection O natural selection and heterozygote advantage O genetic drift O heterozygote advantage

Mosquitoes can carry and transmit many diseases to humansIn the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations . Based on what you've learned about natural selection, in 3-5 sentences, describe how mosquitoes may have come to develop this resistance.

Natural and sexual selection both lead to evolution, but these processes can work against each other. Differentiate between these two forms of selection and give an example of a situation where natural selection reduces mate choice and sexual selection reduces survival.

What do you think would be the genetic and evolutionary consequences to the population if it was not subject to natural selection?
