Learn a gamete definition and what occurs during gamete formation. Before becoming pollen grains, they will undergo meiotic division to form four separate groups of gametes which are called tetrads. When it's warm, it gets larger and floppier to get rid of extra heat. The release of digestive enzymes and the subsequent steps are called the acrosomal reaction and it elicits a response from the egg membranes as well. Gametes are haploid cells , which means that they have only one set of chromosomes. In man, other mammals, plants and many insects like Drosophila, etc., the female has homogametic XX type while male has X and Y chromosomes.
