A chiasma is a physical link between two chromatids of homologous chromosomes, where genetic material can exchange during meiosis. Learn about the discovery, frequency, and regulation of chiasmata, and their role in genetic recombination and chromosomal segregation.
The meaning of CHIASMA is an anatomical intersection or decussation.
Chiasmata are points of contact between non-sister chromatids of homologous chromosomes in meiosis I. Learn how chiasmata form, what they look like, how they are measured, and why they are important for genetic recombination and chromosomal segregation.
A chiasma (plural: chiasmata) is the physical point of contact between paired homologous chromosomes, appearing as a cross-shaped structure. These temporary structures form during meiosis, a specialized type of cell division.
Chiasmata (singular = chiasma) hold the homologous chromosomes together as a bivalent until anaphase I Chiasmata formation between non-sister chromatids can result in the exchange of alleles Electron Micrograph of Chiasmata Skill: • Drawing diagrams to show chiasmata formed by crossing over
