| Modern Genetic Analysis Chapter 4. The Inheritance of Genes Cell Division Figure 4-7. Life cycles of humans, plants, and fungi, showing the divisions in which mitosis and meiosis occur. Note that in humans and many plants, three cells of the meiotic tetrad abort. The abbreviation n indicates a haploid cell, 2n a diploid cell; gp stands for gametophyte, the small structure of haploid cells that will produce gametes. In flowering plants the gametophyte stage is radically reduced, but in others (such as mosses) the gametophyte is the main vegetative stage.
