Aneuploidy
Give this one a try later!
Number of chromosomes IS NOT an exact multiple of n
Types:
Monosomic: 2n - 1 ............ # of chromosomes = 5
Trisomic: 2n + 1 .....................# of chromosomes = 7
Null Mutations

Loss of function alleles that completely block the function of a protein
, synthesis-dependent strand annealing (SDSA)

using information from one chromatid to repair a double stranded break in
another one. This method is known to be error free
(abberant) Euplodiy

Number of chromosomes IS an exact replica of n
Types:
Monoploid: n ......... # of chromosomes = 3
Diploid: 2n ............... # of chromosomes = 6
Triploid: 3n ...............# of chromosomes = 9
Tetraploid: 4n...........# of chromosomes = 12
Nucleotide Excision Repair (NER)

a way of fixing pyrimidine dimers caused by UltraViolet Radiation; And the
generality of the mechanism is proteins recognizing a distortion or a block
to transcription, cutting out the section and then polymerase and ligase
repair the damage.
