Explanation:
Detailed explanation-1: -Polar body formation of a nutritive tissue Rather than degenerating after meiosis, they fuse together into a single triploid cell. Once the ovum has been fertilized and the embryo begins to develop, the polar-body derived triploid cell fuses again, but this time with a single diploid embryonic cell.
Detailed explanation-2: -Polar bodies are byproducts of meiosis and have no biological role in fertilization or in embryo development. Therefore, removal of either the first or second polar body or both for the purpose of genetic testing should not have any deleterious effect on developing embryos.
Detailed explanation-3: -Polar bodies are cells that form by meiosis which differentiate and develop from oocytes.
