Meiotic Meaning: Definition, Examples, and Translations
🧬
meiotic
[maɪˈoʊtɪk ]
Definition
cell division
Meiotic refers to the process of meiosis, a form of cell division that reduces the chromosome number by half, resulting in the production of gametes, or sex cells. This biological process is essential for sexual reproduction and leads to genetic diversity through recombination and independent assortment. During meiosis, one diploid cell divides to form four haploid cells, which are crucial for reproduction in organisms that reproduce sexually.
Examples of usage
- Meiotic division occurs during gamete formation.
- Plants exhibit meiotic processes in their life cycle.
- Meiotic errors can lead to genetic disorders.

Interesting Facts
Biology
- Meiosis results in four daughter cells, each with half the number of chromosomes of the original cell.
- This process is essential for sexual reproduction, enabling genetic diversity.
- During meiosis, homologous chromosomes exchange genes, a process called crossing over, which contributes to variation.
Health and Medicine
- Disruptions in meiotic processes can lead to genetic disorders, such as Down syndrome.
- Understanding meiosis is crucial for advancements in reproductive health and fertility treatments.
- Some cancer treatments aim to target rapid cellular reproduction, similar to what occurs in meiosis.
Psychology
- The concept of genetic diversity obtained through meiotic division can metaphorically relate to creativity and problem-solving in humans.
- Just as meiotic processes produce unique genetic combinations, diverse human experiences foster innovation in culture and thought.
- Research in genetic psychology often explores how variations in genes, stemming from meiotic processes, influence behavior.
Pop Culture
- Meiosis is often referenced in educational cartoons aimed at teaching children biology concepts.
- The concept of genetic variation from meiotic processes can be seen in various sci-fi movies, where characters represent 'ultimate' genetic combinations.
- Meiotic themes are explored in literature, where characters sometimes grapple with their inherited traits and identities.
Origin of 'meiotic'
Main points about word origin
- The term 'meiotic' is derived from the Greek word 'meioun', meaning 'to make smaller'.
- Meiosis was first described in the early 20th century, highlighting its importance in genetics.
- The concept of meiotic division contrasts sharply with mitosis, which is a process of cell duplication.
The term 'meiotic' is derived from the Greek word 'meioun,' which means 'to make smaller' or 'to diminish.' The origins of the word are connected to the fundamental biological process of meiosis, which involves the reduction of the chromosome number by half during the formation of reproductive cells. This concept was first described in the early 20th century as scientists began to understand the mechanisms of inheritance and reproduction. The term has since become integral in the fields of genetics and cellular biology, highlighting its importance in understanding how genetic material is passed on through generations. Meiosis plays a crucial role in the life cycles of all sexually reproducing organisms, ensuring the continuity and variability of species.
