How during gastrulation are the first two germ layers formed? Which are these germ layers?
Answer / Vipin Dahiya
During gastrulation, cells migrate from the blastula stage to create three primary germ layers: ectoderm, mesoderm, and endoderm. The process involves cell movements such as invagination (the formation of an indentation) and epiblast thickening (the thickening of the outermost layer of the embryo).n
