Which model(s) demonstrate(s) how genetic diversity can occur during meiosis? Question 9 options:

Model B only because it is showing crossing over, which is the primary way genetic variation occurs during meiosis.

Both model A and B. Model A shows nondisjunction, which is an error during meiosis that causes genetic variation. Model B shows crossing over, which occurs regularly during meiosis and causes genetic variation.
