Answer: Both are morphogens that provide positional information to cells early in development
Drosophila embryogenesis the process by which Drosophila ( fruit fly) embryos form is a favorite model system for genetics and developmental biology.The study of its embryogenesis unlocked the century-long puzzle of how development was controlled creating the field of evolutionary developmental biology. The small size short generation time and large brood size make it ideal for genetic …
Drosophila melanogaster is a species of fly (the taxonomic order Diptera) in the family Drosophilidae.The species is often referred to as the fruit fly though its common name is more accurately the vinegar fly.Starting with Charles W. Woodworth’s proposal of the use of this species as a model organism D. melanogaster continues to be widely used for biological research in genetics physiology …
Gap gene – Wikipedia
A morphogen is a substance whose non-uniform distribution governs the pattern of tissue development in the process of morphogenesis or pattern formation one of the core processes of developmental biology establishing positions of the various specialized cell types within a tissue.More specifically a morphogen is a signaling molecule that acts directly on cells to produce specific cellular …
Plant hormones (also known as phytohormones) are signal molecules produced within plants that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development from embryogenesis the regulation of organ size pathogen defense stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to …
A gap gene is a type of gene involved in the development of the segmented embryos of some arthropods.Gap genes are defined by the effect of a mutation in that gene which causes the loss of contiguous body segments resembling a gap in the normal body plan. Each gap gene therefore is necessary for the…
