translocation
Reciprocal translocation - ✔✔Exchange of sequence between non-homologues
Robertsonian translocation - ✔✔A special type of translocation that fuses 2
arocentric/telocentric telomeres
, Endopolyploidy - ✔✔In many animals, some cells may be polyploid
Euploidy - ✔✔Gene composed of whole multiple sets of chromosomes from the same species
Monoploidy - ✔✔1N
Rare result of error in mutation
