Various species of the flowering plant of the genus <em>Chrysanthemum </em>have 18, 36, 54, 72, and 90 chromosomes. The variation is likely due to polyploidy.
<h3>What is polyploidy?</h3>
Polyploidy can be defined as the number of complete sets of chromosomes in a given cell of an organism.
A diploid organism contains two complete sets of homo-logous chromosomes in its somatic cells.
Many organisms used polyploidy as an evolutionary strategy for adaptation to challenging environmental conditions.

Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Meiosis creates haploid gametes when<u> </u><u>nuclei re-form</u><u>, and new </u><u>nuclear membranes </u><u>develop.</u>

Meiosis is a form of the mobile department in sexually reproducing organisms that reduces the number of chromosomes in gametes (the intercourse cells, or egg and sperm).
Meiosis is responsible for the formation of sex cells or gametes which are chargeable for sexual reproduction. It turns on the genetic information for the improvement of intercourse cells and deactivates the sporophytic information.
Seeing that cellular division takes place twice at some point of meiosis, one beginning cellular can produce <u>4 gametes</u> (eggs or sperm). In every spherical division, cells go through 4 ranges: prophase, metaphase, anaphase, and telophase.
