Difference Between Telophase 1 and 2

Main Difference – Telophase 1 vs 2

Telophase 1 and 2 are two events in the meiotic cell class. Meiosis is a special type of cell division that only occurs during the production of sexual activity cells. Meiosis produces four, non-identical sex cells. Meiosis occurs in two stages ; litotes 1 and meiosis 2. Each stage is composed of four steps : prophase, metaphase, anaphase, and telophase. cytokinesis occurs at the end of each meiotic stage. Telophase 1 is the concluding gradation of meiosis 1 while telophase 2 is the final step of the meiosis 2. 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.

What is Telophase 1

Telophase 1 is the final stage of the meiosis 1. Telophase 1 follows anaphase 1. During anaphase 1, homologous chromosomes, which are aligned at the cell equator, are separated from each early due to the pull of spindle fibers. A individual spindle roughage is attached to the centromere of each chromosome in the homologous match from one side. therefore, the contraction of the spindle fiber pulls the chromosome towards the pole of the cell. Each chromosome of the homologous match moves towards the opposite poles of the cell at the end of anaphase 1. The motion of chromosomes to the each punt is completed during telophase 1 .
Main Difference - Telophase 1 vs  2 At the end of telophase 1, the nuclear membranes reform, the nucleolus reappears, and chromosomes unwind to chromatids. therefore, two daughter core appear at each opposite pole of the cellular telephone. cytokinesis follows telophase 1, producing two daughter cells. Each daughter cell consists of one chromosome fit of the species. These daughter cells then enter the second stage of the litotes, litotes 2 .

What is Telophase 2

Telophase 2 is the final stage of meiosis 2. Telophase 2 follows anaphase 2. During anaphase 2, baby chromatids are separated from their centromeres and move towards the antonym ends of the cell. here, two spindle fibers are attached to the lapp centromere from both sides. therefore, the contraction of the spindle fibers pulls each sister chromatid to the opposite poles of the cell. The motion of each baby chromatid to the punt is completed during telophase 2. At the end of telophase 2, the nuclear membranes and the nucleoli are reformed, and chromosomes unwind to chromatids. ultimately, two daughter nucleus appear at each pole .
Difference Between Telophase 1 and 2 cytokinesis follows telophase 2, producing two daughter cells. Each daughter cell consists of a sister chromatid from each chromosome of the species. These daughter cells start to specialize into gametes .

Similarities Between Telophase 1 and 2

  • Both telophase 1 and 2 are two steps of the meiotic cell division.
  • During telophase 1 and 2, the movement of the divided genetic material to the opposite poles of the cell is completed.
  • During telophase 1 and 2, the nuclear membranes reform, nucleoli reappears, and chromosomes unwind to chromatids.
  • At the end of telophase 1 and 2, two daughter nuclei appear at each opposite pole of the cell.
  • The daughter nuclei formed in both telophase 1 and 2 are genetically non-identical.
  • The daughter nuclei formed in each telophase are haploid in humans.
  • Both telophase 1 and 2 follow cytokinesis, producing two daughter cells.

Difference Between Telophase 1 and 2

Definition

Telophase 1: Telophase 1 is a stage of the first meiotic division in which the complete campaign of separated homologous chromosomes to the opposite poles of the cell occurs .
Telophase 2: Telophase 2 is a stage of meiosis 2 in which the complete motion of break sister chromatids to the opposite poles of the cell occurs .

Occurrence

Telophase 1: Telophase 1 occurs during the litotes 1.

Telophase 2: Telophase 2 occurs during the litotes 2 .

Movement

Telophase 1: The movement of separated homologous chromosomes to the opposite poles of the cellular telephone is completed during telophase 1 .
Telophase 2: The movement of detached baby chromatids to the opposite poles of the cellular telephone is completed during telophase 2 .

Daughter Nuclei

Telophase 1: Each daughter nucleus formed during the telophase 1 consists of a individual located of chromosomes of the species .
Telophase 2: Each daughter lens nucleus formed during the telophase 2 consists of a single put of sister chromatids from each chromosome of the species .

Correspondence to Telophase in Mitosis

Telophase 1: Telophase 1 is not alike to telophase of mitosis .
Telophase 2: Telophase 2 is exchangeable to telophase of mitosis .

Conclusion

Telophase 1 and telophase 2 are two steps of the mitotic division of cells, which occur during the production of gametes. During telophase 1, the movement of separated homologous chromosomes is completed to the opposition poles of the cell. During telophase 2, the drift of sister chromatids is completed to the antonym pole of the cell. At the end of the telophase 1, two daughter nuclei are formed at each opposite perch of the cell, and each daughter nucleus consist of a single set of chromosomes of the species. At the end of the telophase 2, the formed two daughter nucleus dwell of a individual dress of sister chromatids of the species. consequently, the main difference between telophase 1 and 2 is the events occurring in each footfall.
