Answer: 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.
Explanation: YES AND B/C Crossing over helps to bring about the random shuffling of genetic material during the process of gamete formation. This results in the formation of gametes that will give rise to individuals that are genetically distinct from their parents and siblings.
