Discernment of Fertilized Eggs and Unfertilized Eggs
Unfertilized eggs:
The portion of an egg commonly referred to as the "yolk" is actually only one cell, the female germ cell or egg. Most of the yolk is a nutritive substance, and the nucleus and most of the cytoplasm are concentrated as an irregular white spot floating above the yolk and below the yolk membrane, as shown by the arrows in the figure. Although this egg is hatched but cannot develop, it is called an unfertilized egg.
Fertilized eggs:
The egg of the chicken meets and fertilizes in the infundibulum of the fallopian tube. The fertilized egg continuously divides during retention in the mother, and when the egg is produced in vitro, it has split into a group of cells, which is the blastocyst stage of embryonic development. From the front, the blastocyst covers the disk on the surface of the yolk. The center is the bright area and the edge is the dark area. It is usually called the blastoderm.
