This document contains a 20 question practical test on embryology. The test includes multiple choice and matching questions to assess knowledge of embryonic development stages, germ layer derivatives, and key events in meiosis and mitosis. Test takers are asked to identify structures, match stages and processes to letter choices, and name specific cells and developmental events. The focus is on comprehension of embryonic development from fertilization through formation of the early embryo and germ layers.
