Answer:

6 chromosomes in its egg cell

Explanation:

The Jimsonweed, Datura stramonium, is a plant that produces gametes in order for sexual reproduction to occur. All sexually reproducing organisms undergo meiosis to produce gametes. Likewise, an egg cell (female gamete) will be produced by the Jimsonweed plant via meiosis. Meiosis is a kind of cell division that results in daughter cells with each having their chromosomal number reduced by half.

If the body cells of the Jimsonweed contain 12 chromosomes each, the gametes (egg cell) produced by meiotic division will have 6 number of chromosomes. This reduction in the chromosome number of gametes is important in order to maintain the correct chromosomal number of the offsprings. For example, a diploid organism (2n) undergoes meiosis to produce haploid gametes (n), which will unite with another (n) gamete to produce the 2n offspring.

6 chromosomes. This is because gametes are usually characterised as to having only half the number of chromosomes of the somatic cells.
This is done through meiotic division.

Answer:

Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide.
