When they do lead to chromosomal imbalance, such as increased abnormal chromatids from crossing-overs, they could then lead to chromosomal aberrations. An example of such condition in humans is the chromosomal inversion involving chromosome 9, i.e. inv (9) (p12q13). See also: large-scale mutation. black and decker share price

"WebBased on the number of inverted segments within a chromosome and the location of the inversion points with respect of each other, the inversion may be broadly classified into two types: (1) Single inversion and ADVERTISEMENTS: (2) Complex inversion. 1.
