22.2 Pattern Formation in Drosophila Serves as a Model for the Genetic Control of Development The Development of the Fruit Fly Egg-Polarity Genes Determination of the dorsal-ventral axis Determination of the anterior-posterior axis Segmentation genes Homeotic genes in Drosophila Homeobox genes in other organisms Epigenetic changes in development

22.2 Pattern Formation in Drosophila Serves as a Model for the Genetic Control of Development Egg-polarity genes: Maternal origin: determination of anterior-posterior and dorsal-ventral axes of the embryo Morphogen: protein; its concentration gradient affects the developmental fate of the surrounding region.

22.2 Pattern Formation in Drosophila Serves as a Model for the Genetic Control of Development Segmentation genes: control the differentiation of the embryo into individual segments Gap genes: broad region gap differentiation Hunchback Pair-rule genes: affect alternate segments Segment-polarity genes: development of individual segments

22.2 Pattern Formation in Drosophila Serves as a Model for the Genetic Control of Development Homeotic Genes in Drosophilia: identity of segments Homeobox Genes in Other Organisms: genes encoding DNA binding proteins; these proteins usually play a regulatory rule. Hox genes: encode transcription factors that help determine the identity of body regions Epigenetic Changes in Development

Concept Check 2 Mutations in homeotic genes often cause: the deletion of segments. the absence of structures. too many segments. structures to appear in the wrong places.

22.6 The Development of Immunity Is Through Genetic Rearrangement Antigen: molecules that elicit an immune reaction Antibody: proteins that binds to antigens and mark them for destruction by phagocytic cells The Organization of the Immune System Humoral immunity: the production of antibodies by B cells Cellular immunity: depends on T cells Clonal Selection: primary response, memory cells, secondary response
