der Question 12-6: Giving examples based on genetic data, describe e, how the adoption of agriculture has changed the selective environment for humans. Refer also to Chapters 15-17. Question 12-7: You obtain high-quality, high-coverage genome sequence data from 10 ancient hunter-gatherers and 10 early farmers distributed across Europe. What analyses would you carry out to test ideas about the transition from foraging to farming? Question 12-8: Over lunch, Professor Pangloss (who is fond of exotica) asserts that the steak pies from his local butcher are pure, finest, imported zebu. You are not so sure, but how would you test for adulteration with boring British beef?Explanation / Answer
Question 12-6. The adoption of agriculture changed the lifestyle from nomad to sedentary. The sedentary lifestyle and obesity (one of their consequences generally associated) brought to human so many genetic diseases that were hidden in the nomad lifestyle (due to be recessive characters or that need to be activated by a sedentary life style).
One example is type 2 diabetes that is a genetic disease that is activated by conditions like obesity and a sedentary lifestyle
Question 12-7. I would align and look for SNPs between the 20 genomes searching for conserved SNPs. The idea is that must be SNPs specific to hunter-gatheres and SNPs specific to early farmers that would reflect the change in the style of life from foraging to farming.
Question 12-8. I would do PCR tests with primers specific to Zebu and primers specific to British beef.
If only amplifies the primer specific to Zebu then is right that the steak pies from the local butcher aren’t adulterated.
