WebThese are usually divided into a "short arm" and a "long arm" of the chromosome. The short arm, which is the upper half of the chromosome, is known as the "p arm." The long arm, which is the lower half of the chromosome, is the "q arm." The centromere is the center part of a chromosome that appears "pinched" between the p and q arms. WebA section of the chromosome becomes changed by rotation at 180° is called inversion. The order of the genes in it are reversed. Inversion arises by the formation of loops on a chromosome. Breaks may occur at the point of intersection of the loops (Fig. 43.13). Reunion of the broken ends takes place in a new combination, and inverts. first wish
