Aneuploidy is e presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of e usual 46. It does not include a difference of one or more complete sets of chromosomes.A cell wi any number of complete chromosome sets is called a euploid cell.. An extra or missing chromosome is a common cause of some genetic disorders. In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is left out during DNA replication. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome.. e smallest single base deletion mutations occur by a single base flipping.
