Examples

• The blastodiscs in chicken eggs are visible as small white spots on the yolk.
• During incubation, the blastodiscs undergo rapid cell division to form the embryo.
• Researchers examined the blastodiscs under a microscope to study early development.
• The formation of blastodiscs is a critical stage in avian embryogenesis.
• Multiple blastodiscs can sometimes develop in a single egg, leading to unusual embryonic patterns.
