Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

During inversion a segment of chrom osome 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 $\mathrm{DEF}$ inverted. The new arrangement will be $\mathrm{ABCFEDGH}I.\mathrm{It}\mathrm{is}\mathrm{a}$ chromosome aberration entailing two 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.
