Question
Chapter 10, Problem 2RQ
Summary Introduction
To describe:
The crossing over and determine the stage at which meiosis occurs. Also, name two functions of chiasmata.
Concept introduction:
The crossing over takes place between the two chromatids in order to exchange the genetic material. The chromatids are attached by the common point known as chiasmata. It is a process take place in the prophase I of meiosis I.
