Question

Polar bodies are formed by

• A. Mitosis in males
• B. Mitosis in females
• C. Meiosis in males
• D. Meiosis in females
• E. None of the above

Answer 1

The correct option is D Meiosis in females

The formation of ova in the ovary from primordial germinal cells is said to be oogenesis. It is completed in three steps:

(1) Multiplication phase: The germinal epithelium cells of the ovary multiply by mitotic divisions to form a small cluster of cells known as follicles. A single cell from the follicle differentiates and form oogonium.

(2) Growth phase: The oogonium grows in size and attains maturity and is called primary oocyte.

(3) Maturation phase: The primary oocyte undergoes the first meiotic division and produces a larger secondary oocyte and a small polar body.

So, the correct answer is option D.
