What distinguishes prophase 1 of meiosis from prophase of mitosis?

In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.

How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
Meiosis 1 us the same as what other reproductive process?
during metaphase 0_______0
How is meiosis related to genes?
Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication)) in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells. segragation of alleles occur too.
What happens to a parent cell at the end of meiosis 1?
the formation of two daughter cells with genetically different material (from each other and from parentbecause of the crossover of the chromatids during prophase 1, the chromosomes at the end of Meiosis 1 will be unique in each cell.This is the reason why siblings don't look the same, yet they look similar to each other and resemble slightly to their parents
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.
When does crossing over happen in mitosis 1?
Mitosis does its crossing over in prophase
Which of the following occurs in meiosis but not mitosis?
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
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
Each phase of mitosis?
The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
What is the first phase in meiosis?
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.
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.
Meiosis consists of two cell divisions what are they?

What is the longest phase of meiosis?
The longest phase in meiosis is Meiosis 1.
How does metaphase 1 differ from metaphase of mitosis?
It differs because in meiosis the cell in prophase 1 just crosses over and that is really the only difference in the two.
