- - - - powerful tool for genetic analysis
      - insertion sequence and transpons.
    - - many man made
      - UV light x-rays, radiation from radioactive substances
      - certain chemicals.
  - - - may code for protein with bad active site.
- - - - diploid to haploid
  - - - pollen is used to fertilize its own eggs.
    - - probability
  - - - expressed.
  - - - certain mutations will likely occur
      - dominance is complex
        
        different phenotyes are possible.
  - - - first filial generation
        
        F2 generation.
    - - RR or rr
    - - Rr
- - - - Recombinant chrmosome
        
        from crossing over .
      - linked together.
        
        heterozygous for 2 traits.
      - usually don't undergo independent assortment.
  - - - independently or dependent.
  - - - duplicated during S phase.
  - - - prophse I
      - farther apart genes are the greater chance.
      - synaptonemal complex is formed.
- - - - forms replicon.
      - free nucleotides diffuse/pair with bases.
        
        ribonucletides
        
        primer DNA acts as substrate
        
        semiconservation replication.
        
        for DNA polymerase.
- - - - result of complex metabolic process.
      - Eg: R in flower trait.
        
        red color
- - - - DNA nucleotides
        
        guides the construction of RNA /proteins
        
        alleles
        
        Genotypes
        
        types of alleles
        
        Phenotypes
        
        expression of alleles
        
        arises by mutation and new sequence is new allele
      - Identical nucleotides
        
        identical physically.
- - - - sometimes tetraploid
        
        don't undergo
        
        S phase.
    - - Change in chromosome number.
      - 2 chromatids may remain together.
      - Down syndrome.
    - - alleles of both parent
      - all genes in nucleus undergo this.
    - - maternal inheriance
      - megagamete.
    - - pollen parent ? ovule parent.
    - - almost undectectable
        
        if detected, eliminated.
      - respiration DNA replication cellulose synthesis.
