Question
Chapter 4, Problem 1P
Summary Introduction
To determine: Any meiotic products that did not undergo a crossover in the meiosis illustrated and colors convention used.
Introduction: Crossing over produces new allelic combinations
Expert Solution & Answer
Explanation of Solution
Morgan suggested that, when homologous chromosomes pair at meiosis, the chromosomes occasionally break and exchange parts in a process called crossing over and this physical exchange of chromosome segments. The two new combinations are called crossover products.
Pictorial representation:
Fig.1: Crossing over produces new allelic combinations
The exchange of parts by crossing over may produce gametic chromosomes whose allelic combinations differ from the parental combinations.

Students have asked these similar questions
In Figure 4-6, why does the diagram not show meiosesin which two crossovers occur between the same twochromatids (such as the two inner ones)?
In Figure 4-3, would there be any meiotic products thatdid not undergo a crossover in the meiosis illustrated? Ifso, what colors would they be in the color conventionused?
Considering Figure 2-8, is the sequence “pairing →replication → segregation → segregation” a good shorthand description of meiosis?
