Mistakes such as nondisjunction can occur during meiosis. This is the result of chromosomes failing to separate equally during either anaphase.

During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
A synaptonemal complex disappears during?
After the pachytene stage, or in the end of it.
Does the nucleus disappear during mitosis and meiosis?
Yes, the nucleus dissipates during late prophase and early metaphase in mitosis, and during Prophase 1/diakinesis of meiosis.
Crossing over occurs in?
Each chromatid can synapse with any one it want/chooses.
What happens during synapsas in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. It does this as the homolog pairs match up, which means there are 4 chromosomes of like, but possibly unique, DNA data in the grouping. This allows the cell. as it proceeds through Anaphase 1 and Anaphase 2 to separate the individual chromosomes first into 2 pairs then as individuals, which inturn adds to the variability as 1 chromosome goes to each daughter cell. .
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
Recombination occurs during?
meiosis
During what event of meiosis will chiasmata be observed?
during the pachytene stage of prophase-1 of meiosis -1 of meiosis ,the X shaped structure chiasmata is observed
WHEN DO Chromosomes decondense into diffuse chromatin?
At the beginning of Prophase 1 during meiosis. It occurs in a sub-stage of Prophase 1 called Leptonema.
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
A synaptonemal complex disappears during?
After the pachytene stage, or in the end of it.

Crossing over occurs in?
Each chromatid can synapse with any one it want/chooses.
During which stage of meiosis do synapsis and the formation of tetrads occur?
The formation of tetrads are formed during p1(prophase 1)

Does crossing over occur in meiosis?
yes crossing-over occurs in meiosis also known as genetic drifting
Does homologous chromosomes pair up during meiosis 1?
Yes, during prophase I.
