| 1. | However it does create abnormal second polar bodies and therefore possible aneuploid zygotes.
|
| 2. | ANI-1 is also crucial for segregation of polar bodies during meiosis.
|
| 3. | Polar bodies are nonfunctional and incapable of being fertilized.
|
| 4. | In theory, molecular analysis of polar bodies may include epigenetic profiling in the near future.
|
| 5. | The pictured oocyte has an extruded polar body at about 12 o'clock indicating its maturity.
|
| 6. | However, chromosomally abnormal polar bodies are not guaranteed to induce the development of an abnormal zygote.
|
| 7. | The oocyte now undergoes its second meiotic division producing the haploid ovum and releasing a polar body.
|
| 8. | The oocysts have a polar body and a prominent residuum but lack micropyles, sporocyst residua or Stieda bodies.
|
| 9. | Potentially, polar body biopsy may be used for molecular analysis, and can be used for preimplantation genetic screening.
|
| 10. | Therefore, the formation of the first polar body is an especially important factor in forming a healthy zygote.
