_________________ involves breeding mice that have had a specific gene removed from their genome. In contrast, _________________ involves inserting a new gene into an animal's genome
A) Transgenics; biomutation
B) Gene Knockout; transgenics
C) Biomutation; transgenics
D) X-inactivation; biomutation
Answer: B
Rationale: Gene knockout (KO) studies involve removing a specific gene thought to be involved in a trait (such as intelligence) and testing the effects of removing the gene by comparing behavior of animals without the gene with those that have it. In contrast, transgenic animals have had a new gene inserted into their DNA.
