Reproduction (Strange Sexual Reproduction Strategies (Sex reversal: change…

- - - - contains fragmentation and regeneration
      - splitting or separation of a parent organism into 2 individuals of roughly the same size
    - - forms a colony
      - stony corals: buds form and remain attached to parents
- - - - Oogenesis (all primary have been produced by birth)
        
        Primary Oocyte (diploid): happens in utero, doesn't complete meioisis 1, present at birth
        
        Completion of MEIOSIS 1 at puberty
        
        MITOTIC DIVISIONS
        
        Secondary Oocyte (haploid): Doesn't complete meiosis 2, one cell gets all the stuff, one gets pretty much nothing
        
        Oogonium (diploid)
        
        Ovulation/sperm entry
        
        MITOTIC DIVISIONS
        
        completion of MEIOSIS 2
        
        Primordial germ cell
        
        FERTILIZED EGG
      - Spermatogenesis (occurs throughout males life)
        
        Primary spermatocyte
        
        MEIOSIS 1
        
        MITOTIC DIVISIONS
        
        Secondary spermatocyte (2 haploid cells)
        
        Spermatogonia (diploid)
        
        MEIOSIS 2
        
        MITOTIC DIVISIONS
        
        Early spermatid (4 haploid cells)
        
        Spermatogonial stem cells (diploid)
        
        Differentiation
        
        Sperm cells
