Summary Introduction

To determine:

The pattern of segment polarity gene expression be normal if one or more gap gene were not expressed easily.

Introduction:

Segment polarity genes are a gene related to tissue pattern in every repeated unit of a segmented organism. Segment polarity is the last step in embryogenesis. GAP genes are involved in the formation of embryo. These genes are characterized because of mutation in that gene which causes loss of segment. Gap genes regulate the work of pair rule genes and homeotic rule genes
