Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.

Does alignment of tetrads at metaphase plate occur in mitosis?
No, it occurs in Meiosis II, Metaphase
Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
How does the alignment of chromosomes differ at the equator between metaphase of mitosis and metaphase of meiosis 1?
In prophase the membrane of nucleus disappears, then the nucleus too, chromosomes unwrap, collocation of spindle apparatus is completed. In metaphase: chromosomes line up on equatorial cell-plate. there is very little difference
What do homologous chromosomes do in prophase 1?
Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.
What happens during synapsis in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. During synapsis is when tetrads form.
Do tetrads form in mitosis or meiosis?
Meiosis
What is the functional role of forming tetrads in meiosis and or mitosis?
Tetrads only appear in meiosis. The tetrad is the joining of four chromosomes in prophase I of meiosis. Two male duplicated chromosomes and two female chromosomes. The most important role of tetrad formation is ' crossing over. ' This is the exchange of genetic information between the male and female chromosomes. The material, whole genes, is physically swapped between the male and female chromosomes.
How is forming tetrads in prophase 1 different from mitosis?
Tetrads don't form in mitosis. Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination. The products of meiosis are gametes which ensure genetic diversity in subsequent generations. In mitosis, the daughter cells are genetically identical to the parent cell. No genetic recombination occurs in mitosis.
When do chromosomes form tetrades?
Chromosomes form Tetrads during meiosis in Prophase I
What is the activity of chromosomes in metaphase 1 of meiosis?
In Mitosis during Metaphase, the chromosomes line up on the metaphase plate, but without their homologues. In Meiosis during Metaphase I, the tetrads line up on the metaphase plate. Then it's back to double-stranded chromosomes lining up in Metaphase II. I
The chromosomes separate and move in opposite directions during?
IN Mitosis, the Siter chromatids separate in anaphase. IN Meiosis, the tetrads separats in anaphase I and the siter chromatids separates in anaphase II
Does alignment of tetrads at metaphase plate occur in mitosis?
No, it occurs in Meiosis II, Metaphase
How does the chromosome grouping in step two of mitosis differs from that in step two meiosis?
In step two of mitosis (also known as metaphase) the chromosomes line up on the equator of the cell and in meiosis step two (also known as metaphase I) Tetrads line up on the equator of the cell.
What occurs in meiosos but not in mitosis?
lining up of tetrads, crossing over, and separation of homologous chromosomes.
The process where replicated homologous chromosomes are linked to form tetrads is called?
Meiosis Stage II.
