Question 2: You are out at a park and see someone walking their dogs. This person has 3 dogs that are all the same, but they have different fur colors. One is black, one is
brown, and one is light brown. Explain how a change in the DNA makes this possible?
(Fur color in dogs is controlled much the same way as it is in in deer mice.)

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
