WebSep 24, 2010 · Jargon alert: Meiosis is a special type of cell division that produces gametes (typically egg and sperm cells in animals or spores in ferns) – these are haploid cells as they have half as many chromosomes … WebThe process of producing eggs in the ovary is called oogenesis. Eggs, like sperm, are haploid cells, and their production occurs in several steps that involve different types of cells, as shown in Figurebelow. You can follow the process of oogenesis in the figure as you read about it below. Oogenesis.
