We all had thought that bees or any specific insects or animals could not reproduce without a male, but we were wrong about it. The species has advanced a unique survival method that permits female employee bees to squat in overseas foreign nests and lay viable eggs with none assistance from males. The study published in has PLoS Genetics. The researchers take the primary steps in figuring out the evolutionary records of these reproductive quirks.
The fact is that men and women of an animal species do it sexually so. Generally, that is what honeybees do too. Sperm from a male drone fertilizes a queen egg, and he or she sends out a chemical signal, or pheromone, that renders employee bees, all-female, sterile once they discover it.
However, the Cape honey bee a subspecies which live in a unique area of incredible diversity called the Fynbos ecoregion. The site is along the southwestern tip of South Africa. In some cases, female workers can produce offspring of their own.
How Do Honeybees Reproduce Without a Male?
Female honeybees are capable of reproducing asexually. They lay eggs that get fertilized through their DNA, which becomes new worker bees. The female worker bees develop their ovaries to a greater extent then the other bees do.
Most of the bees rely upon their queen’s fertilized eggs to keep the population going, so the worker bees do not need to give much energy for growing their reproductive organs so they can smoothly go in and lay the eggs without being detached.
So those eggs hatch as fully-fledged worker bees. However, the worker bees do not do an awful lot of work. They go away maximum of the foraging to the natives of the colony they have infiltrated and achieved the rewards. They can keep laying their eggs competing the ones laid by their unsuspecting step-mom, and sooner or later, the glut of lazy invaders ends in the fall apart of the colony.
By far, the research suggests that a single gene might be the reason which caused this strange behaviour. But the studies did by webster and his colleagues recently identified several regions of the Cape bee genome, which are markedly different from their close relatives, standing out in sharp contrast to the many many genes they share in common. And for now, the scientists are not exactly sure why and how these genes changed behaviour so drastically.
And by now, scientists have not sorted out why there is probably an evolutionary gain for a female bee capable of reproducing without a male bee. In intense conditions and not using a male, it can imply her species’ survival. But then again, self-fertilization, the epitome of inbreeding, ought to depart her offspring’s greater liability to disorder and different threats.
In the end, The question of why this population of honeybees in South Africa has advanced to breed asexually remains a mystery. But expertise the genes concerned bring us toward to expertise it. This observe will assist us in apprehending how genes manipulate organic techniques.
