AP Biology · Unit 5: Heredity
5.1 Meiosis
In short
You are expected to understand that meiosis ensures the formation of haploid gamete cells in sexually reproducing diploid organisms. You must know the specific steps of Meiosis I (including homologous chromosome pairing, synapsis, chiasmata formation, alignment at the metaphase plate, and separation of homologous chromosomes while sister chromatids remain attached) and Meiosis II (where sister chromatids are pulled apart to form four haploid daughter cells with unduplicated chromatids).

What else do you need to know about Meiosis?
Furthermore, you must be able to compare mitosis and meiosis, recognizing that both utilize a spindle apparatus to move chromosomes, but differ in the number of cells produced and the genetic content of the resulting daughter cells.
How is Meiosis tested on the exam?
The primary skill assessed in this topic is explaining biological concepts and processes (Skill 1.B). You may be asked to analyze and construct models to predict the haploid results of meiosis. Exam questions will frequently use the command verbs 'Explain' (requiring information about how or why a process occurs using evidence or reasoning) and 'Describe' (providing relevant characteristics). A common focus is comparing the outcomes and phases of mitosis and meiosis.
