Cape Town bees in South Africa can create perfect clones on their own

This threat comes from a rival subspecies called the South African Cape Bee, which can create perfect clones. In the past 30 years, an individual bee has been found to have been cloned millions of times. Cape bees can infiltrate the nests of lowland bee opponents and can produce one copy after another without the queen bee. Originally, if different species of bees can perform their duties and live in peace, it seems that there is no problem, but the cause of the demise of the African lowland bee hive is that the clone of the Cape bee in South Africa only eats but does not do it.

A new study has discovered the genetic basis of the clonal adaptability of the Cape honey bee in South Africa. According to this research, unlike most animals and even the queen bee in the bee hive in Cape Town, South Africa, female worker bees do not re-adjust the DNA of their eggs.

This means that the worker bees will continue to create perfect copies of themselves every time they reproduce. Researchers say that bypassing the DNA recovery process is different from anything they have ever seen. One researcher said that although this process is incredible, it is also incredibly dysfunctional. In the process of egg formation, genetic recombination is usually required to fix the chromosomes together, but somehow, bees can lay eggs without this process.

Bee workers and other social insects can reproduce through a form of asexual reproduction called parthenogenesis. This process allows females to produce female offspring from unfertilized eggs. Each time an offspring is born, the single-parent worker bee will copy the chromosomes she got from her parents. The genetic material from these four chromosomes is usually reshuffled, which should be to ensure that in the case of one parent, the future offspring are genetically different. However, because only two of the four chromosomes were selected and there was no new genetic material introduced by the sex partner, an average of one-third of the genetic diversity was lost with each shuffle.

In the Cape Town honeybees, the worker bees have a genetic mutation that allows them to lay their eggs parthenically with all the genetic material of the four chromosomes, which means they will not throw away any chromosome. How they do this, we don’t know.
