Mitosis does its crossing over in prophase
prophase 1.
Each chromatid can synapse with any one it want/chooses.
DURING PROPHASE I:Crossing over happens in chromosomes where genetic information is swapped from chromosome to another at a chiasma (chiasmata for multiple crossing over sections)Cell is Diploid 46 chromosomesDURING PROPHASE II:No Crossing over at this point, as it has already happened during prophase I.Cell is Haploid 23 chromosomesRead more: What_is_the_difference_between_prophase_I_and_prophase_II_of_meiosis
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis
Crossing over occurs during Prophase I of meiosis.
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
Mitosis does its crossing over in prophase
prophase 1.
Yes, only prophase 1 of meiosis. Crossing over occurs when homologous pairs of chromosomes (tetrads) line up in prophase I. In prophase II there are no tetrads left, only sister chromatids, so there is nothing there to recombine with.
Each chromatid can synapse with any one it want/chooses.
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.

The exchange of a corresponding segment between homologous chromosomes is known as genetic recombination or crossing over. This process occurs during meiosis and results in the exchange of genetic material, contributing to genetic diversity among offspring.
