Clintock (1938), in her study of a paracentric in-version in chromosome 4, found that in 41 per cent of the cells with anaphase I bridges the acentric fragment was not free but was attached to a normal chromatid.

Hum. Inversions of the X-chromosome often lead, in contrast to inversions of the autosomes, to the development of gene-function irregularities. Paracentric inversions do not include the centromere and both breaks occur in one arm of the chromosome, while pericentric inversions include the centromere and there is a breakpoint in each arm of the chromosome (Fig.

About 20 of all conceptions have a chromosomal disorders ,but most of these are spontaneously aborted so that birth frequency is 0. If the inversion coexists with another rearrangement in the same chromosome, it is a complex inversion.
