Fatima Riyadh - I learned that meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. It results in a variety of genetics and it is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Overall, this lesson strengthened my understanding and recognition of how intricate and organized cell processes are to keep our bodies healthy.

At anaphase II, sister chromatids separate. ... In contrast to mitosis, the sister chromatids of each homolog remain attached to each other. At meiosis II the sisters now separate to opposite poles.

Meiosis is a type of cell division in which the number of chromosomes is reduced by half. Meiosis is specific to gamete producing cells in the gonads. Meiosis begins with a diploid cell and ends with four haploid cells. These cells eventually differentiate into mature sperm or egg cells. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair. Two cell divisions occur during meiosis, meiosis I and meiosis II.

  • Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This is due in part to crossing over during meiosis.
Meiosis I begins after DNA replicates during interphase of the cell cycle. In both meiosis I and meiosis II, cells go through the same four phases as mitosis - prophase, metaphase, anaphase and telophase. However, there are important differences between meiosis I and mitosis

Meiosis is different from mitosis in such that they happen in sex cells and split two times after replicating the right amount of DNA. I learned that 
Prophase 1 = chromosomes condense, centrioles move to the poles, spindle fibers appear, and cross over the genes
Metaphase 1 = homologous chromosomes align along the equator in pairs; random orientation occurs
Anaphase 1= chromosomes are not torn apart but instead pulled as a whole 
Telophase 1= chromosomes prepare for meiosis II as they may not decondense and nuclear structures may not reappear

Meiosis II is technically mitosis but all 4 haploid cells end up with a genetically unique material 

as for the chiasmata specifically, With the help of synaptonemal complexes, chiasmata are formed in which an “x” is shaped by both chromosomes where genetic exchange takes place. It sets the stage for the new chromosomes with derived parts. This means genetic exchange is achieved.

I also learned that through the homologous chromosomes and the fact they are not bound to a certain formation, many possibilities and variations can be achieved. As for crossing over, it created countless mixtures as genes could be passed down from the uncle, mother, father, paternal and maternal grandparents. For random orientation, the line-up of the homologous chromosomes can take up any line-up and that alone would result in 8 million different possibilities.

The DNA molecule of one of the chromatids is sliced. Following that, another cut is made in the DNA molecule of a non-sister chromatid. The DNA of one chromatid connects to the DNA of the non-sister chromatid. After then, the genetic material may be transferred between the paternal and maternal chromosomes. This is known as crossing over. The homologous chromosomes are no longer intimately linked after crossing over, but the connection between the non-sister chromatids remains, resulting in an X-shaped structure known as a chiasma. The chiasma is a link between homologous chromosomal pairs that lasts until late metaphase I.]]> 2021-10-31 13:59:42 UTC https://padlet.com/njidaniel/zbzslpilfoajqu3l/wish/1856691001 Saif Laith https://padlet.com/njidaniel/zbzslpilfoajqu3l/wish/1858120116  Meiosis is the type of cell division that produces gametes.

The technique for crossing over is as follows:
Homologous chromosomes bind together to form a bivalent chromosome in a process known as synapsis (or tetrad)
Non-sister chromatids separate and recombine with their homologous partner, willingly transferring genetic material (crossing over)
The non-sister chromatids are joined in an X-shaped pattern, and the sites are lead.
Chiasma binds homologous chromosomes together as a bivalent until anaphase I.]]> 2021-11-01 16:44:34 UTC https://padlet.com/njidaniel/zbzslpilfoajqu3l/wish/1859313293 Nasser Faisal nasserfaisal197 https://padlet.com/njidaniel/zbzslpilfoajqu3l/wish/1859342728 I learned that meiosis is the type of cell division that produces gametes.
