After a germ cell replicates and grows in females, it forms two primary what?

• A. oocytes
• B. polar bodies
• C. zygotes
• D. spermatocytes

Answer: (A)

Verified step by step guidance

1. Understand the context: In female gametogenesis (oogenesis), a germ cell undergoes replication and growth before meiosis begins.
2. Recall that after DNA replication, the germ cell is called a primary oocyte, which will enter meiosis I.
3. Recognize that the primary oocyte is the cell that results from the growth and replication phase before the first meiotic division.
4. Note that polar bodies are small cells produced later during meiosis as a result of unequal cytokinesis, not immediately after replication and growth.
5. Conclude that the correct term for the cells formed after replication and growth in females is 'primary oocytes'.
