Hold your breath! Y Chromosomes on verge of getting extinct, What will happen to men?
In a major setback for Male population, Y chromosomes present in human cells are rapidly decreasing. It may be worrisome for biologists because men are on the verge of getting extinct from this planet.
This claim has been made in science journal Conversation. According to scientists, this biological phenomenon can take 46 million years to occur. According to the scientists, this may be a long time for people, but if you keep this in mind, think about this aspect that life on Earth is available for three and a half billion years, then this time frame seems to be very worrying.
The embryonic XY chromosomes develop in the male, whereas embryos without the Y chromosomes that are XX chromosomes develop into a female infant.
Scientists have claimed that 166 million years ago, in other words the Earth at the time was the first mammalian was developed, the number of protozoa chromosomes was equal to X chromosomes.
According to scientists, Y chromosomes follow a basic rule. Where there are two copies of other chromosomes in our cell, there is only one copy of the Y chromosomes, which a father transmits in his son during the reproduction process. This means that the Y chromosomes can not take part in genetic retention in every generation.
Genetic recumbency is the ribs of genes, which cause bad genes to fall out. Due to the absence of genetic retention, the quality of Y chromosomes gets worse in the long run and the result may be that the genes are completely out of the genome system.
Although scientists have argued that end of the Y chromosomes does not mean that the species of men will end. Research has claimed that there is a need for male and female for the process of reproduction in the speech where the Y chromosomes have ended. In these cases, the genes, whereby the male embryo is formed, are constructing the male embryo with the help of the other genes. This means that these species are producing male fetuses without Y chromosomes.
