(Q001) Mutaons occur in DNA throughout the cells of our bodies, but mutaons do not always lead to evoluonary changes. Describe the circumstances under which mutaons will have a real evoluonary effect on future generaons. Describe the circumstances under which mutaon will not have a real evoluonary effect on future generaons. Evolution is defined as a change in allele frequency. There is only one way in which mutations will have a real evolutionary effect on future generations is if occurs in in a Gametes / sex cell, these types of mutations are passed down onto future generations.

Mutations can also be caused by large errors which causes a section of chromosome to be moved elsewhere. All of these circumstances will not have a real evolutionary effect on future generations. Ques 1 / 1 pts tion 2 Your Answer: (Q002) Describe a hypothecal scenario of natural selecon for a trait. Be sure to describe each of the key elements (such as how the trait varies in the populaon, how the trait factors into resource compeon, and how the trait frequency changes over mulple generaons). A a hypothetical scenario of natural selection for a trait would be lactose persistence. Lactose is a sugar in milk. In order for you to drink milk or enjoy dairy made products, you would need lactase which is an enzyme. Every mammal is born with a gene that allows them to tolerate lactose until they are weaned off of their mother's milk. Usually after they are weaned off of their mother milk the genes that allowed them to tolerate lactose is turned off, but some humans mostly people of European decent, and , and people in some parts of east African have developed lactose persistence. Experts believed that this lactose persistence Started to happen during the time that humans started to domestication cows and other similar farm animals. Which might mean there was some evolutionary advantage in it. I remember one of my former professors stating being lactose persistence would serve as an advantage during times where there was no clean water, or during times or starvation. People who could drink milk would have been able to Survive and have offspring who were lactose persistence, while people who where lactose intolerance would have died off because they wouldn't have anything to drink or eat.
