Answer:

The chains of meiosis refer to the eight phases of said cellular process and are the following:

First division:

Prophese I --------- Metaphase I ----------- Anaphase I -------------- Telophase I -------- ---------

Second division:

---- Profase II -------------- Metaphase II -------------- Anaphase II ------------ ---- Telophase II

Explanation:

Meiosis happens in the germ cells of organisms and is formed by two consecutive divisions. Before the meiosis, an S phase of DNA synthesis occurs, with which each couple chromosome enters meiosis, during the first division the number of chromosomes is halved, and later in the second division the chromatidia will be separated, In this way each gamete has a single set of chromosomes complete with chromosomes.

Meiosis occurs when there is formation of reproductive cells happens.

Meiosis is divided into two division each of is divided into four stages, total eight stages, which is called meiosis chain.

Stages of Meiosis

Meiosis I

  • Prophase I- nuclear membrane dissolve, crossing over starts.
  • Metaphase I- spindle fiber emerge and chromosomes align in one line.
  • Anaphase I- spindle fiber contract, similar chromosome move to opposite pole.
  • Telophase I- nuclear membrane develop, cell divides and formation of two haploid daughter cells occur.

Meiosis II

  • Prophase II-  chromosomes starts to condense, nuclear membrane dissolve and centromere moves to opposite direction.
  • Metaphase II- chromosomes align, spindle fiber attached to them.
  • Anaphase II- spindle fiber contract, sister chromatids move to opposite pole.
  • Telophase II- chromosome decondense, nuclear membrane form and four haploid cell forms.

Thus, that's how the formation of four haploid daughter cells happens.
