Ch. 16 Genetics, image, image, referring to alleles, one type of mutation,…

- - - - plants pollen fertilize own eggs
    - - give possible gene types
  - - - 2 identical alleles for gene
    - - 2 different alleles for gene
    - - F1
        
        offspring of crossbreeding
      - F2
        
        interbreed F1 offspring are
    - - parents
    - - neither parental trait dominates
  - - - Homozygous recessive
- - - - something that causes mutations
    - - contain genes that code enzymes
      - cutting sequence out & splicing it elsewhere
    - - like an insertion sequence
      - genes for proteins not associated w transposition
  - - - nature, position, extent
  - - - never lead to sex cells
  - - - piece of DNA lost
    - - DNA tangles and breaks
      - then repairs backwards
    - - addition of extra DNA
- - - - forned from crossing over & recombination of alleles
      - last two crossing
    - - first two crossing
- - - - aka maternal inheritance
      - zygote obtains genomes from maternal
    - - presence of spots or sectors
    - - both parent alleles transmitted equally
  - - - a change in chromosome # per nucleus
    - - wild-type alleles duplicate of it
    - - more than two sets of chromosomes
    - - multiple copies constitute
