Question

Identify the stage of follicle where primary oocyte undergoes first meiotic division.

Also mention the products of this division.

Answer 1

The primary oocyte completes its first meiotic division within the Graafian follicle (also known as the mature tertiary follicle).

Products of the First Meiotic Division

1. First Polar Body: A tiny, haploid cell that contains very little cytoplasm and typically degenerates.
2. Secondary Oocyte: A large, haploid cell that retains the bulk of the nutrient-rich cytoplasm.
