Question

Quizplus · Accepted Answer

Polar bodies are small cells that are formed and subsequently discarded in the process of oogenesis, which is the production of an ovum or egg cell in females. They contain the haploid number of chromosomes but do not develop into ova. Specifically, one polar body is produced during the first meiotic division, and then this polar body can divide again during the second meiotic division, leading to a total of three polar bodies (one from the first division and two from the second division of the original polar body). This process ensures that the egg cell retains most of the cytoplasm and organelles, maximizing the resources available to the zygote upon fertilization.
