But remember, if a high stress level continues for a long period of time, or if potential problems from stress continue to interfere with activities of daily living, it is important to reach out to a licensed mental health professional, such as a psychologist.
Noun. 1. meiosis - (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants). miosis, reduction division.
In mitosis, both the parent and the daughter nuclei are at the same ploidy levelâdiploid for most plants and animals. Meiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division.
