Given below is a representation of a kind of chromosomal mutation. What is the kind of mutation represented?
(4) Reciprocal translocation
(3) During inversion a segment of chromosome gets inverted in the process of reattachment. Thus a chromosome having the genes A B C D E F G H I in linear order may get the segment D E F inverted. The new arrangement will be A B C F E D G H I. It is a chromosome aberration entailing twp breaks in a chromosome followed by a reversal of the segment and consequently of the gene sequence in the segment. Pericentric inversion includes the centromere in the inverted segment, whereas paracentric inversions do not.
