Prophase 2 definition full#

The main difference between telophase 1 and 2 is that homologous chromosomes are separated from each other during telophase 1 while sister chromatids are separated at the centromere during telophase 2. Telophase 1 is the final step of meiosis 1 while telophase 2 is the final step of the meiosis 2. Cytokinesis occurs at the end of each meiotic stage. Each stage is composed of four steps: prophase, metaphase, anaphase, and telophase. Meiosis occurs in two stages meiosis 1 and meiosis 2.

Meiosis produces four, non-identical sex cells. Meiosis is a special type of cell division that only occurs during the production of sex cells. Telophase I is marked by the arrival of chromosomes at opposite poles of the cell along with cytokinesis after separation leading to two daughter cells having a single set of chromosomes, all set to enter meiosis II.Telophase 1 and 2 are two events in the meiotic cell division. Anaphase I is marked by the homologs moving apart while the sister chromatids are still linked. Meta phase I marks the lining up of homologous pairs at metaphase plate for separation with random orientation of pairs leading to the development of gametes with random homologous sets. After crossing over, the chromosomes go to the spindle while the two homologs of a pair retreat to the opposite poles. The cross-shaped linkage of the homologous chromosomes is called Chiasmata which links the homologs even after the breakdown of the synaptonemal complex. Cross over takes place in the presence of a protein is known as Synaptonemal complex which binds the homologous pairs to each other. The position in which the homologous pairs exchange parts is known as Cross over.

Prophase I mark the condensation of the chromosome which further aligns to form homologous pair to match up to the two at their corresponding positions along their full length. Thus in meiosis, the diploid cells experience replication of DNA which follows 2 rounds of cell division resulting in four haploid gamete cells. To keep up the diploid nature after the fertilization of egg and sperm, they must be haploid containing single set chromosomes. A parent cell has a diploid arrangement of chromosomes that is 23 sets of chromosomes for a sum of 46 chromosomes. The meiosis cell division aims to deliver the daughter cells with half the number of chromosomes as the parent cell. Meiosis is the specific kind of cell division that happens just for the production of sex cells or gametes within the individuals, sperms, and eggs. Meiosis is a complex procedure than mitosis which explicitly happens for gamete cells. In the human body, this kind of cell division happens many times like substitution, wound mending, and development of tumors.

Mitosis has four phases Prophase, Metaphase, Anaphase, Telophase for a single round. Mitosis is a eukaryotic cell division that forms two daughter cells from a single parent cell which have the exact genetic segment as the parent cell. It happens primarily in two different ways: Mitosis and Meiosis. The procedure by which the cell divides to develop two or more daughter cells is called Cell division. Cell division is the core of reproduction. Reproduction is the principal procedure in a creature through which parents will pass on their genes into their offsprings.
