Each chromatid can synapse with any one it want/chooses.
chromosomes exchange corresponding segments of DNA
Crossing over occurs between nonsister chromatids during prophase I of meiosis. It occurs at an X-shaped region called a chiasma.
It takes place in prophase 1 of meosis
prophase1
prophase 1
prophase I
Before crossing over, interphase I takes place. Crossing over occurs during prophase I. Metaphase I occurs after prophase I.
Crossing over occurs during Prophase I.
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis
Prophase I of Meiosis.
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.
Crossing over occurs during Prophase I.

Crossing over occurs during Prophase I.
Crossing over occurs during synapsis, prophase I.
Crossing over occurs during Prophase I.
Crossing over occurs in meiosis. There is no need for crossing over in mitosis.
Crossing over occurs during Prophase I of meiosis.
