germ band造句

• Germ band retraction returns the hindgut to the dorsal side of the posterior pole and coincides with overt segmentation.
• Genes that were enriched in the developing embryos at the germ band stage are involved in cellular and organismal development.
• Kalinka " et al " . sequenced the transcriptome of six " Drosophila " species over developmental time, identifying the most conserved gene expression in mid-development during the arthropod germ band developmental stage.
• For example, Klaus Sander noticed that the  incredible variation in larvae and adults of insects occurs after they " develop from nearly identical rudiments in the germ band stage " . is the idea that early embryos of different species display divergent forms but their morphologies converge in the middle of development, followed by a period of increasing divergence.
