Maternal genes are expressed in the unfertilized egg and provide cues for early embryonic development, including the spatial organization of the embryo. Gap genes, segmentation genes, and segment polarity genes are all involved in later stages of embryonic development. Homeotic genes are involved in determining the identity and development of specific body segments.
