Which of the following is common to the development of both birds and mammals? a. holoblastic cleavage b. epiblast and hypoblast
Amanda [17]

Epiblast and Hypoblast are common in the development of both birds and mammals.

Hypoblast is the second layer of the embryonic disc that creates the yolk sac, Epiblast is one of the two layers that creates the three basic germ layers (ectoderm, definitive endoderm, and mesoderm), amnionic ectoderm, and extraembryonic mesoderm.

The embryonic disc is made up of two parts: epiblast and hypoblast.

The epiblast and hypoblast are formed by layering the core cell mass. As a result, the inner cell mass gives rise to the epiblast and hypoblast.

Additionally, epiblast cells are topped by hypoblast cells.

Both layers are formed before implantation and gastrulation.

The blood gets oxygenated and returns to the heart via the pulmonary vein (the only place in the body where a vein carries oxygenated blood) and pushed into the left atria the pumped into the left ventricle and out to the body via the aorta.
