Yes dear friends, the the polar bodies not only help in getting rid of half chromosomes and and maintaining the requisite haploid number, but also help conserve much needed cytoplasmic and nutrient resources for the development of oocyte and perspective zygote.
A polar body is a small haploid cell that is formed concomitantly as a egg cell during oogenesis, but which generally does not have the ability to be fertilized. When certain diploid cells in animals cytokinesis after meiosis to produce egg cells, they sometimes divide unevenly. For more details consult https://en.wikipedia.org --wiki -- Polar.
