The Points Where Chromosomes Have Physically Crossed Over are Known

Question

The points where chromosomes have physically crossed over are known as:
A) Centromeres
B) Kinetochores
C) Chiasmata
D) Diplonema
E) Pachynema

Accepted Answer

The points where chromosomes have physically crossed over are known as chiasmata. This occurs during meiosis and is important for genetic diversity as it causes a recombination of genetic material between homologous chromosomes. Centromeres and kinetochores are structures involved in cell division, while diplonema and pachynema are stages in meiosis.
