How are male gametes formed

WebThe gametes produced in meiosis are all haploid, but they're not genetically identical. For example, take a look the meiosis II diagram above, which shows the products of meiosis for a cell with 2 n = 4 2n = 4 2 n = 4 2, n, equals, 4 chromosomes. Each gamete has a unique "sample" of the genetic material present in the starting cell. 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
