Verified
Drosophila developmental mutants of ____ genes produce larvae with mirror image segments.
A) gap
B) pair-rule
C) segmentation
D) paternal effect
E) segment polarity
Segment Polarity
Genetic and cellular mechanisms that establish anterior-posterior orientation within each segment of a developing embryo, crucial for proper patterning.
Drosophila Developmental Mutants
Genetic variants of fruit flies used to study developmental processes and genetic regulation during growth.

Final Answer :
E
Explanation :
Segment polarity genes are responsible for defining the anterior and posterior polarities within each segment of Drosophila larvae. Mutations in these genes can result in larvae with mirror image duplications of segment parts, indicating their crucial role in segment patterning.
