- - - - Short generation time
        
        Large numbers of offspring
        
        Controlled mating (self-pollination or cross-pollination)
  - - - Having two identical alleles
      - Homozygous dominant: PP
      - Homozygous recessive: pp
    - - Having two different alleles (Pp)
  - - - P generation: Parental generation (original parents)
      - F1 generation: First filial generation (offspring of P)
      - F2 generation: Second filial generation (offspring of F1)
- - - - Occurs in body (somatic) cells
      - One division (PMAT once)
      - Produces 2 identical cells
      - Each cell has 46 chromosomes (diploid)
  - - - Occurs in sex cells (gametes)
      - Two divisions (Meiosis I and II)
      - Produces 4 unique cells
      - Each cell has 23 chromosomes (haploid)
- - - - Heterozygote shows an intermediate phenotype (blending)
    - - Both alleles are fully expressed
  - - - Blood types:
      - AB: Codominant, universal recipient
      - O: Recessive, universal donor
