To most animal, life of a new student is careful afterbirth and an oocyte are united in wedlock and come by. Cell of every kinds of sex contains a group of chromosome each, give consequently new individual two groups of chromosome, call diploid number. Queen bee and worker bee are female bee, they come from oosperm, their body cell has the chromosome that diploid counts, altogether 32 (2n ~ 32) . Drone is never oosperm development and become, accordingly, the chromosome that they come from multiple of parent square sheet only (N ~ 16) .
This kind of monoploid of the bee and the circumstance with concomitant diploid, produced two kinds of special appearances, involve firstly not the development of oosperm, matter to the maturity of spermatozoon secondly.
The maturity of eggThe ovarian canal forehead with ovarian traceable of queen bee egg closes the egg former cell of end. Become divided of former cell hyperplasia becomes these egg the grow oocyte with bigger oocyte and lesser posse or weigh alimentary cell. They are being wrapped by follicular bursa respectively, make the room of two photographs adjacent. They increase gradually, when they drop to near ovarian canal lower end, oocyte is abrupt sponge grow oocyte, those who achieve it is the biggest individual, next the egg carapace that egg holds bursa cell in the arms to secrete a springiness, rise egg bag.
Development has 16 to be opposite in the egg of the move or two groups of chromosome. Every come from the mother of queen bee to one of chromosome, another comes from father
Egg is in before yielding, experience successive nuclear dissension twice even. When maturity breaks up or weighing meiosis for the first time, every lean together to two of chromosome, at this moment didymous chromosome may have exchange, next each other are apart, shift arrives the one aspect of the matter of spindle silk. A pair of some that which medium chromosome walks along spindle silk are specific upright, another pair of medium where encounter with it, it is random completely. In different egg, originate the chromosome of queen bee mother and originate all possible combination of the chromosome of queen bee father can happen. So, the egg that queen bee produces is not identical on heredity.
Break up twice continuously, and chromosome undertook ego duplicates only, the result forms the nucleolus of 4 new cells, every nucleolus has a group (16) chromosome. Among them 3 cellule are called extremely body, atrophy is dropped, leave next nucleolus to live, become the former nucleus of egg.
The maturity of spermatozoonThe mature process of apian egg and general animal are identical, but the mature process of apian spermatozoon differs with general animal however. Drone climbs the sperm former cell in the crime bolus canaliculus of bolus, pass mitosis for many times above all, next every cell increases bulk to become cell of primary essence mother (N) . Do not experience meiosis in spermatozoon maturity process, somebody thinks cell of mother of a primary essence forms cell of a sperm only, also somebody thinks to be able to form two sperm cell (N) . Its complete set chromosome passed every spermatozoon, so, millions upon millions spermatozoon of each drone does not have the difference that goes up hereditarily.
