men have been working well in the field of continuation of the family. However, in recent decades, malfunctions began to be observed. The “wrecking” began to engage in the Y chromosome.
Man, this is an individual with a y-chromosome. Rather, its sperm carries a pair of chromosomes-X and Y. In the egg of a woman-two X-chromosomes, resembles XRUST. In a much smaller Y chromosome there is a Sry gene, which is a switch of testicular development.
It is unfortunately established that over time the Y-chromosome loses its parts of itself. Having laid the computer model of the consequences, biologists found that after 11 million years it will simply disappear.
The loss of the y-chromosomes is a non-trivial question, because what it preserves-or loses-can affect everything: from the risk of cancer before people will multiply in future.
However, some archaeologically excavations showed that some mammals continued to produce males after their Y chromosome disappeared. True, the current men are already paying for their defects.
X-chromosome carries about 900 genes, and y only 55. A comparative analysis of mammals shows that after our line separated from the platypus about 166 million years ago, Y began to lose about five genes every million years. Scroll through this line forward, and after 11 million years the register will reach zero-geological heart rhythm.
Among optimistic facts-the Japanese prickly rat and several types of racks flourish today at all, they managed to redo the traditional scheme of the creation Yaichk.
In general, in 11 million years, evolution will find a way out.
