If a cell fails to go through cytokinesis after completing meiosis II, what term best describes the genetic makeup of that cell at that point?
Added by Alicia R.
Step 1
Meiosis consists of two rounds of cell division (meiosis I and meiosis II) that result in four haploid cells from one diploid cell. Each haploid cell contains half the number of chromosomes as the original diploid cell. Show more…

A skin cell from a human female undergoes mitosis. For an unknown reason, the centromeres of one of the two number 4 chromosomes fail to separate. Describe the resultant chromosome number of the two daughter cells. Indicate the genetic make-up of each cell. Suppose this happened to a single cell in reproductive tissue undergoing meiosis II (the cell went through Meiosis I normally). What would be the chromosome number of the resulting cells from this cell? Provide a diagram to illustrate this. If instead of a problem with Meiosis II, the problem was with homologous chromosomes not separating in Meiosis I, what would be the complement of chromosomes for each of the resultant gametes produced? Provide a diagram to illustrate this. For all scenarios, assume that the cells finish mitosis and meiosis even if not viable due to an abnormal chromosome count.

After telophase I of meiosis, the chromosomal makeup of each daughter cell is A) diploid, and the chromosomes are composed of a single chromatid. B) diploid, and the chromosomes are composed of two chromatids. C) haploid, and the chromosomes are composed of a single chromatid. D) haploid, and the chromosomes are composed of two chromatids. E) tetraploid, and the chromosomes are composed of two chromatids.
