Meiosis - Coggle Diagram

- - - - 2 haploid daughter cells with duplicated chromosome
  - - - 4 genetically different haploid daughter cells UNDUPLICATED CHROMOSOMES
- - - - group of 4 chromatids
    - - Exchange of DNA 1st source of variation
  - - - Seperated into 2 haploid daughter cells
- - - - XX (F)
      - XY (M)
    - - Similar but not identical
      - Length, shape size, centromere position are the same
      - Carry genes controlling inherited things (Same/ different version of genes)
        
        Alleles
      - 1 maternal, 1 paternal
  - - - 2n (two sets of chromsomes)
      - 46 in humans
      - Somatic cells
    - - n (one set of chromsomes)
      - 23 in humans
      - Gametes
- - - - Internal/external signals
        
        (external) cytochrome c initiates apoptosis --> activates capsases (protein)
        
        (internal) mitochondria release cytochrome c
    - - Form apoptotic bodies
      - Blebbing of plasma membrane
      - DNA fragmentation
  - - - Due to stress
      - Physical injury, chemical agents
      - Swelling & LYSIS of cell
      - Cell fragmentation
      - Inflammatory response
