WebThe mechanism by which homologous chromosomes heterozygous for inversions accomplish such pairing in the meiotic sequence is depicted in Figs. 12.13 and 12.15. The products of crossing over and subsequent stages of meiosis are different for the two types of inversions. Types of Inversions: Inversions can be of two types: WebInversion involves at least two breaks in a chromosome; the broken segment rotates 180° and is then reunited at the two break points. Types of Inversion: Based 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:
