Precursors of one type of these cells are classified by their appearance as type A dark, type A pale, or type B. That type of these cells is targeted by nonoxynol-9. A method for a “hyperstimulation” technique uses clomiphene citrate to collect a type of these cells which then undergoes the ICSI procedure. One of these cells expresses CatSper (10[1])channels that mediate capacitation. (-5[1])A “calcium wave” triggers the acrosomal (-5[1])reaction (10[1])in one of these cells, causing the release of hyaluronidase (10[1])at the zona pellucida (10[1])of another type of them. Asymmetric division of one type of these cells forms (10[1])polar bodies. (10[1])The synaptonemal complex forms to allow crossing-over during the division of these cells, one type of which arrests (10[1])in prophase I. For 10 points, meiosis produces what type of cell that includes eggs and sperm? ■END■ (10[1])
