Summary Introduction
To explain:
The effects on meiosis if a meiotic cell is unable to make proteins of the synaptonemal complex.
Introduction: Meiosis is a type of cell division which produces four haploid cells and every cell is genetically different from the parent cell. Meiosis starts with a diploid cell and gives rise to four haploid daughter cells. Meiosis is divided into meiosis I and meiosis II. Meiosis I is further divided into prophase I, metaphase I anaphase I, and telophase I. Meiosis II is further divided into prophase II, metaphase II, anaphase II, and telophase II.

From this point on, meiosis is very similar (but not exactly similar) to what happened in mitosis. How many copies of each type of chromosome end up in the daughter cells of meiosis when it is complete?
Given that a diploid cell will undergo meiosis and give rise to gametes (egg or sperm cells), where in the body would you expect this cell to be located?
How would Shugoshin does not break down after anaphase I of meiosis affect the outcome of mitosis or meiosis?
