Question

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

Accepted Answer

Crossing over is one of the most important events in meiosis because it produces new arrays of alleles on chromosomes. This is because crossing over results in the exchange of genetic material between homologous chromosomes, which can lead to the creation of new combinations of alleles.
