GENETICS overview

YO MendeL!!!
1. By the power vested in me.... I deduce LAWS!!!
  1. Law of independent assortment
  2. Law of segregation
    Attachments:
    - (INcmplete note) GENETICS- 2 laws of mendelism (warning: crude humour)
2. Simple genetics
wait...WHAT'S genetics?
1. it's all in the genes...
  1. how it's made...
    1. meiosis
    2. mitosis
    3. cell cycle... just when ya think that interphase is gd for nothin'...
    4. cell division basically,,, MAHN is this mindmap pretty
  2. DNA & RNA structure
  3. The process...
    1. DNA replication
    2. DNA to protein
      1. transcription
      2. translation
Advanced genetics
1. beyond mendel
  1. only alleles for a SINGLE gene
    1. incomplete dominance
    2. co-dominance
    3. mutiple alleles
    4. pleiotropy
      1. when 1 gene, can affect many characteristics. like a BAWSE
  2. when TWO or more genes r inv, in det a particular pheno
    1. epistasis
    2. POLYgenic inheritance
      1. wen 2/more genes can affect 1 pheno
        aka d OPPOSITE of pleiotropy
        prod QUANTITATIVE characters. ie MANY/continuous variation
        eg skin colour. v dark (AABBCC), intermediate (AaBbCc) ,v light (aabbcc) etc..
        cumulative effect like a BOSS
2. lethal alleles
3. sex-limited & sex influenced inheritance
how EXACTLY does the chromosomal basis... TRANSMIT GENES frm parents to offspring?
1. linkage recombinatn n mapping
"I'm too awesome for the status quo" important EXCEPTIONS... to d STANDARD MODE OF INHERITANCE
1. sex determinatn n sex chrom
2. when genes rebel...
  1. chromosome mutations (like hot pyro)
    1. aneuploidy n polploidy
  2. EXTRACHROMOSOMAL inheritance
    1. organelle heredity, & maternal effect
    2. MITOchondrial DNA, genomic imprinting & fragile-X syndrome
