What is the point in making polar bodies in meiosis?

Going from memory, long time since studied biology.





IT does seem at first like a waste of energy %26amp; genetic material.





The main genetic advantage i remember is that as the chromosomes split and the double Hellix reform's twice, this is an efficent way to repair minior gene copy mistakes / damage and to early on weed out %26amp; lose / discard major problems while their is still time an energy for more ovem develoment. Resulting in potentualy more healthy first, second, third %26amp; so on generations of offspring.





I hope this interpretation of past llessons help.





Happy New Year 2008What is the point in making polar bodies in meiosis?
This is one of those fields that is still developing and over the next few years, more and more information will flow into. As for my knowledge, the polar bodies are created in Meiosis as excess. The main point of Meiosis was to produce the egg, and the egg needs a little more raw material than normal meiotic daughter cells can offer, so the polar bodies, which would normally go on to make normal gametes, give off part of their nutrients/material to contribute to the egg cell. This also ties into the though of altruism, the contribution of something to another organism, in return for a negative impact upon the giver. It proliferates the genes that these polar bodies have in common. So the point of polar bodies are to donate what is needed to the egg cell.
