What type of environment do you think the lactase-persistent gene (genes code for proteins/enzymes) came from? In other words, what type of environment would be able to digest lactose be advantageous?
Homework Answers
- The lactase persistent gene came from the Turkish ethnic group of people locating in the northern parts of central Asia. The domestication of cows, goats and sheep lead to these mutations in the gene that produce lactase enzyme.
- In other words the type of environment and human culture with highly access to the domesticated dairy animals will be advantageous to lactose tolerant.

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their

What genes (or kind of genes) will you focus on in your investigative research? Provide 2-3 reasons for your choice of these gene/s. Starting with the bone sample itself, what methods will you use to get DNA that you can sequence? Which “ingredients” in your lab reactions will determine which gene or genes are copied? How is it that these ingredients are able to target a specific gene? What method will you use to see if your efforts to copy...
