Scientists have cloned goats so they can take out a protein in the goats’ milk and use it to make medicine. The goats are raised in a laboratory. The medicine that is produced can help with certain diseases that affect humans. Which best describes a disadvantage of this scenario?

The goats will have more genetic variation.
The goats will become infected with the human diseases.
There are unknown health risks to the goats.
There could be many health risks to drinking the goats’ milk.
