When Does Crossing Over Occur ... Home Science Biology Cells. When Does Crossing Over Occur in Cell Division? When Does Crossing Over Occur in Cell Division? Crossing over begins very early in the prophase I stage of meiosis. During prophase I, pairs of homologous chromosomes exchange lengths of their genetic material. Crossing over leads to ...

en.wikipedia.org/wiki/Chromosomal_crossover

Chromosomal crossover (or crossing over) is the exchange of genetic material between two homologous chromosomes non-sister chromatids that results in recombinant chromosomes during sexual reproduction.It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis. ...

In particular, crossing over sometimes occurs during mitosis, and sometimes does not occur in meiosis (such as in male fruit flies). ————— Mitotic Crossing-Over. It was a surprise for geneticists to discover that crossing-over can also occur at mitosis. Presumably it must take place when homologous chromosomal segments are ...

Crossing over occurs during prophase I, one of the longest phases of meiosis. Recombination or crossing over has rarely been observed during mitosis. It is completed before the cell proceeds to either metaphase I or to the second meiotic division.

well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occurCrossing over occurs ...

♦ Meiosis can be divided in two stages: meiosis I and meiosis II. It is in the prophase of meiosis I that crossing over of the chromosomes takes place, and the homologous chromosomes are separated into two daughter cells. In meiosis II, the sister chromatids are pulled apart from each other to give rise to four haploid daughter cells.
