Crossing over is one of the most important events in meiosis because __.
A) homologous chromosomes are separated into different daughter cells
B) the number of chromosomes allotted to each daughter cell must be halved
C)sister chromatids must be separated into different daughter cells
D) it produces new arrays of alleles on chromosomes and contributes to genetic diversity
Homework Answers
Crossing over is one of the most important events in meiosis because it produces new arrays of alleles on chromosomes and contributes to genetic diversity.
(Crossing over is the process of exchange of DNA segment in between non sister chromatids of homologous chromosomes during Tformation gametes. This exchage of DNA results in genetic diversity in organism, which make organism more superior or different than other, sometimes it may have negative effects)

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...
