Chromosome mutation inversion
WebFeb 12, 2010 · The majority of the nine visible inversions occurred along the chimpanzee lineage, but inversions on chromosomes 1 and 18 are specific to the human lineage. These findings indicate that inversions are a type of rearrangement that occurs quite frequently in primate chromosomal evolution. WebThe most common of these rearrangements is an inversion of a region of chromosome 16 (written as inv(16)). An inversion involves breakage of the chromosome in two places; the resulting piece of DNA is reversed and reinserted into the chromosome. Less commonly, a translocation occurs between the two copies of chromosome 16 (written as t(16;16)).

WebHumans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 8, one copy inherited from each parent, form one of the pairs.
