Got Milk? Got Allergies? October 3, 2012: People with milk allergies often turn to products like rice and soy milks. But now there is a new source of hypoallergenic milk available from genetically-modified cows. New Zealand scientists have produced a calf that gives milk lacking a certain protein, called beta-lactoglobulin (BLG), that causes an immune response in people with milk allergies. To get the milk this way, scientists inserted a specially designed gene into cow embryos that prevented the production of BLG. Hypoallergenic milk could be a boon for the 2 to 3 percent of babies in developed countries that have allergies to proteins in milk.
According to the prompt, how was this new hypoallergenic milk produced?

Scientists cloned the DNA of a cow that did not produce BLG and insert into cow embryos.

The scientists removed a specific gene so the embryos would not produce a certain protein.

The scientists removed a gene from the DNA of the mother cow so she would produce embryos that lacked the gene for BLG production.
