Meiosis

Meiosis is a specialized type of cell division that reduces the chromosome number by half, resulting in the production of four haploid gametes from a single diploid cell. This process is crucial for sexual reproduction and contributes to genetic diversity through the recombination of genetic material.

Meiosis meaning with examples

• In humans, Meiosis occurs in the formation of sperm and eggs, allowing for the genetic material from two parents to mix during fertilization, contributing to genetic diversity in the offspring.
• Researchers at the university studied Meiosis in fruit flies to understand the mechanisms that lead to chromosomal abnormalities, which can result in genetic disorders in offspring or infertility.
• During Meiosis, homologous chromosomes are separated in a series of stages, including prophase, metaphase, anaphase, and telophase, each playing a vital role in ensuring proper chromosome distribution.
• The failure of Meiosis can lead to aneuploidy, where cells have an abnormal number of chromosomes, which is often observed in conditions like Down syndrome.
• Meiosis is often contrasted with mitosis, the latter being the process that results in the division of somatic cells, allowing for growth and tissue repair rather than reproduction.
