A protein that could destroy all men on Earth

We may be headed for an all - female future civilization . For one childlike reason : woman have two ex chromosomes , while men have only one . For the most part , this is n’t a problem . But now it seems that this transmissible setup could top to a scenario where the riddance of one key protein could wipe out all men on the face of the planet , but leave woman perfectly level-headed . Or so a grouping of investigator says .

In certain respect , piece and womanhood are like fruit flies . They secern their genders through a paired set of chromosomes . Double X chromosome mean that the baby aviate ’s apparel should all be a powder pink . An X chromosome paired up with a Y chromosome means that the baby fly can be pressured by his beginner to be an eagle sentinel . The same move for humans . Two Xs make a girlfriend . An X and a Y make a male child .

The problem is , there is some important material on the X chromosome and while girls ' Xes work as a team , a boy ’s single X has to struggle through alone . This means that some wellness conditions due to defective X chromosomes are almost unknown in girls . If something ’s untimely in a gene on one X chromosome , the other can ill-use up . If a boy gets an X with a problem , there is no back - up .

Even in good for you males , the deficiency of an extra X may mystify a trouble . Genes ca n’t just sit around looking pretty . They have to be expressed ; to form a functional product . There ’s a whole mechanism that goes into taking the data on a piece of DNA and turn it into , say , a hand . If that mechanism is weak the man , or fly , it belong to is in full-grown hassle . In humans and flies , males only have one X that can be expressed , half the figure that females do .

Scientists have suspect that males had a sure protein that increase the reflection of the disco biscuit chromosome , but the increase was thought to be belittled . of late some research worker totaled up the manifestation of the cristal chromosome , compare to the other chromosome , in male fruit fly . They found that the protein just about doubled the formula of the chromosome . Given the magnitude of the change in reflexion , the researcher believe that suppression of this protein could be the reason many medical condition are find more usually in valet de chambre than they are in adult female .

The protein is call MSL , which sounds unobjectionable . It stand for Male - Specific Lethal , which emphatically does not voice innocuous . Without this protein , the male would die . Although it has only been studied in flies , researchers think that it works in human male person just the way it work in yield flies . If there were a way to completely curb it , all men ( And women , I think . And tent-fly . ) would be in a great good deal of trouble .
