What is the Function of Polar Bodies?

AI Thread Summary
Polar bodies, though often considered nonfunctional, have several potential roles in reproduction. They may serve diagnostic purposes, and their nuclei can be used in enucleated eggs to create viable zygotes. Additionally, there is a suggestion that the second polar body might play a role in embryo cleavage and establishing polarity. The mechanism for determining which cells become polar bodies is still unclear, with some speculation about randomness in the process. Overall, while polar bodies are small and seemingly insignificant, they may have important functions in embryonic development and reproductive technologies.

hi

our genetics teacher has asked us about possible functions of polar bodies (if they are unfunctional, why do not they fully disappear but limit their smallness in some way; etc) and I could only find some diagnostic usages of polar bodies and that their nuclei could be inserted into enucleated eggs to produce viable zygotes.

I also wonder if there is any mechanism for determining which of the cells will become the polar body or if it's completely random.

does anybody know anything about this subject?

thanks a lot
in our lecture we discussed some functions of polar bodies. an interesting one was that second polar body may be required for cleavage of the embryo(creating the polarity of it)
 
cool, I didn't know that!
