During oogenesis will the genotypes of the first and second

During oogenesis, will the genotypes of the first and second polar bodies be identical? Explain.

Solution

No. The oocyte development occurs through meiosis, which divides the chromosomes. Crossing over of homologus chromosomes also takes place which adds differences in the daughter cells produced. Moreover, the first and secondary polar bodies are produced in different phases of meiosis. As they divide before the mitotic phase of meiosis, the two polar bodies cannot br identical.
