What’s the difference between innate and learned behavior? Which one has a genetic basis?

Learned Behavior is MODIFIED BY EXPERIENCE (Genetics + Environment)
What are the 4 classical methods for determining whether or not a behavior has a genetic basis?
Selection Experiments
Cross-Fostering Experiments (Common Garden)
Regression Analysis
Hybridization
Describe a “selection” experiment? What does it attempt to determine?
The mice nest building selection experiment attempts to determine if nest building trends are heritable and genetic
High cotton gathering mice were bread together
Low cotton gathering mice were bread together
Control groups randomly mated
How can a microarray be used to identify genes important in regulating a behavior? How would you set up the experiment?
Microarray can be used to identify genes important in regulating a behavior by identifying which genes are being expressed
