Explanation: 

Detailed explanation-1: -The small white spot on the yolk is call the germinal disc. The germinal disc is where the female’s genetic material is found.

Detailed explanation-2: -The germ spot is the white spot on the yolk. The non-fertile germ spot contains only the female’s cells and looks like a solid white spot. In a fertile egg the germ spot contains both the female and male cells.

Detailed explanation-3: -The chalazae (plural) are rope-like structures made of protein that act as a support system for the yolk. It keeps the yolk suspended in the center of the egg and safe from pressing against the shell or settling on one side of the egg. When cracking an egg, there’s really no need to remove the chalazae.

Detailed explanation-4: -Blood spots are usually found in egg yolks and occur due to ruptured blood vessels in the hen’s ovaries or oviduct. On the other hand, meat spots are typically found in the egg white and are formed from pieces of tissue.

Detailed explanation-5: -The egg white is known as the albumen, which comes from albus, the Latin word for “white.” Four alternating layers of thick and thin albumen contain approximately 40 different proteins, the main components of the egg white in addition to water.
