Homeotic Gene Silencing in Drosophila
Drosophila homeotic genes Polycomb proteins were first discovered as
repressors of homeotic genes that specify segmental determination in Drosophila
(Garcia-Bellido, 1975; Lewis, 1978) (Figure 1.1). It has been shown that the
homeotic ...

Exploring Genetic Mechanisms
As we have seen, we know much about how the segmentation genes initiate
homeotic gene expression in flies. The gap genes play a particularly important
role in controlling where the homeotic genes are expressed along the A-P axis.

Genetics: Analysis & Principles:
The role of homeotic genes in determining the identity of particular segments has
been revealed by mutations that alter their function. For example, the Antp gene
is normally expressed in the thoracic region. The Antennapedia mutation causes

Essential Developmental Biology
A homeotic mutation is one that can convert one body part into another. How this
can happen is explained by our simple model. Suppose that the organism of Fig.
2.15 is a mutant and that the second gene in the series is permanently inactive ...
