- what characteristics are shared among bird embryos, pig embryos, and human embryos?What are the correct pairings of developing and embryonic structures in the gastrulation of chickens? Multiple answers is possible. If no correct option is given write the proper pairings. a. Epiblast – ectoderm b. Secondary hypoblast – endoderm c. Primary hypoblast – endoderm d. Migrating cells - mesodermExamine whether the statement "Because of the many later developmental transformations that produce the elaborately structured organs, the body plan set up during gastrulation bears little resemblance to the body plan in the adult is true or false.

How much yolk protrudes through the blastopore of a frog gastrula How much yolk protrudes through the blastopore of a frog gastrula? Chickens lack a larval stage. How do they compensate for this?Suppose we isolate one blastomere from a 4-cell stage sea urchin embryo.
