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.

In what phase of meiosis is chromosome recombination most common?
Construct a table for the different stages of meiosis, giving the number of chromosomes per cell and the number of DNA molecules per cell for a cell that begins with 4 chromosomes (two homologous pairs) in G1. Include the following stages in your table: G1, S, G2, prophase I, metaphase I, anaphase I, telophase I (after cytokinesis), prophase II, metaphase II, anaphase II, and telophase II (after cytokinesis).
