Question

what happens to the polar bodies during oogenesis?
they change to new reproductive cells.
they fuse with the ovum to form a zygote.
they are absorbed by the ovum as nutrition.
they develop into secondary ova.

Explanation:

During oogenesis, polar bodies are formed as by - products. They do not become reproductive cells (so the first option is wrong). A zygote is formed by the fusion of sperm and ovum (so the second option is wrong). Polar bodies do not develop into secondary ova (so the fourth option is wrong). Polar bodies are small cells that are eventually absorbed by the ovum, which can use them as a source of nutrition.

Answer:

They are absorbed by the ovum as nutrition.
