Solution

The correct option is B Meiosis
The sexual reordering of DNA is the basic switching of maternal and paternal DNA. Such crossing over of two chromosome inherited from one's parents occurs during meiosis. When a pair of chromosomes "recombine" during sex cell formation, in the simplest case, genetic information on the paternal chromosome is switched with information on the maternal one, and vice versa. The two 'daughter' chromosomes that result are not identical to either of the original parental ones.
