Flashcards

What are primordial germ cells (PGCs)?

The earliest cells that will eventually develop into sperm or eggs, thus playing a crucial role in reproduction.

What do PGCs mature into?

Sperm and eggs, produced by the PGCs. They fuse to create a zygote, initiating a new organism.

What is a zygote?

A new fertilized egg formed by the combination of a sperm and an egg.

What's the significance of PGCs in reproduction?

Through the creation of sperm and eggs, PGCs ensure the continuation of life across generations by passing genetic information down.
