Chapter 20, Problem 1CQ

a.

Summary Introduction

To determine: Whether mutation has occurred in the segmentation gene or the homeotic gene if three abdominal segments are missing.

Introduction: In Drosophila, regulation of the process of pattern formation and morphogenesis occurs with the help of certain genes such as segmentation genes and homeotic genes. A mutation in these genes leads to alteration in the patterns of segmentation and morphology of the organism.
