If a cell has a diploid number of 8 (2n = 8) before meiosis, how many chromosomes will be in each of the four daughter cells aft
Naddik [55]

Answer:

The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Explanation:

If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.

If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.  

The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.  

If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).  

But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Mrrafil [7]

Answer:

interphase

Explanation:

Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.

There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include  cell grows, DNA replicates and prepare itself for mitosis.

Hence, the answer is "interphase".
