During meiosis, crossing over occurs during prophase I. It is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes, which contribute to genetic diversity.

Crossing over is the process of swapping DNA sequences between the chromatids of paired homologous chromosomes. This process occurs during the prophase of meiosis I.

Prophase I. During which step of cell division does crossing over occur? Prophase I. What is the evolutionary purpose of cells that undergo crossing over? To increase genetic diversity. During which phase of meiosis does DNA begin to condense? Prophase I. What is the female gamete called? Ovum.

-Crossing over occurs during Prophase I of meiosis? True. True or False?-Crossing over allows the reassortment of linked genes? True. True or False?-In meiosis I, the homologous pairs of chromosomes are separated when the cell divides and the result is two cells, each of which contains 23 chromosomes.

Crossing Over. Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched. The two chromosomes contain the same genes, but may have different forms of the genes.
