crossing over occurs in what stages Meiosis?

Expert Solution

Diploid number: Cells that contain two copies of each chromosome, one from mother and one from father is described as diploid cells. It can be an organism or a cell. In humans there is diploid number of chromosomes in most of the cells. The number of chromosomes in total in the diploid cells are described as 2. In humans, diploid cells contain 46 chromosomes (2n).

Haploid number: Cells that have half the number of chromosomes than the diploid cells is called haploid number. Gametes contain half the number of chromosomes than those in diploid somatic cells or non-sex cells. The number of chromosomes is represented by n. In humans, n= 23.

Crossing over:

Crossing over in meiosis occurs in Prophase-I stage. Crossing over homologous chromosomes occurs and two non-sister chromatids pair up with each other exchanging different genetic material segments leading to formation of two recombinant chromosome sister chromatids and also this results in increased genetic variation.
