Then, instead of 20, you have 30 foxes. All of the mice are gone in a matter of weeks. So the Foxes start to slowly drop out. Then, theres not much for the bears to eat, so the bears start dying. Then, the humans can't hunt bears. It sets the whole chain of the forest off. Next, the humans will switch to dears, and all the dears will be killed off... etc... etc... Make sense? Got a question? Message me for more details and more questions!

Cons: The tests can incite discrimination towards her in the workplace, and having it known she has a risk for breast cancer can severely increase the cost of insurance.
C) Genetic sequencing could affect the frequency of genetic diseases because the test could point out --- I can't finish because I have to go. I'm so sorry, reask the url of this question and ask someone to finish. Have a nice day!
