WebThese cells are the gametes. “Gamete” is a generic term. An egg is a gamete and so is a sperm cell. Eggs and sperm cells are strikingly different in morphology (this is called _____), but sometimes, the gametes cannot be told apart (_____). The fusion of gametes, also called *_____, thus leads to a cell, which holds two sets of WebIn addition, during meiosis, crossing-over between homologous chromosomes provides a method to increase genetic varied among the resulting gametes. Abominable mobile division in either mitosis or meiosis can result in unusual distributions on chromosomes, and the consequences can range from innocuous to lethal. new online account
