Crossing Over is One of the Most Important Events in Meiosis

Question

Crossing over is one of the most important events in meiosis because _________________.  
A) it produces new combinations of alleles on chromosomes
B) homologous chromosomes must be separated into different daughter cells
C) the number of chromosomes allotted to each daughter cell must be halved
D) homologous chromatids must be separated into different daughter cells
E) the number of chromosomes allotted to each daughter cell must be split in fourths

Accepted Answer

Crossing over is the exchange of genetic material between homologous chromosomes during meiosis. This results in the production of new combinations of alleles on chromosomes, which contributes to genetic diversity. The other choices are also important events in meiosis, but they do not directly relate to the purpose of crossing over.
