Definition

A point where two structures cross each other, often used in anatomy and genetics to describe the intersection of nerves or the contact point between chromatids during cell division.

Example

During meiosis, the chiasma forms between paired chromatids, allowing for genetic exchange.

Conversation

Have you ever heard of the term chiasma in genetics?

Yeah, I remember it has something to do with chromosomes during meiosis.

Exactly! It's where the chromatids cross over, forming a chiasma.

Right, it's fascinating how that affects genetic diversity!
