Image Everyone’s love – mosquitos. This is to do with the mosquitos that carrie malaria. Apparently by genetic modification – shredding the X chromosome – scientists have managed to make it that more male mosquitos are produced as offspring. Unfortunately, the only way for this to happen is for the GM mosquitos to be released in more numbers than ‘normal’ males so that they can out-mate with the females. In lab tests, after 4 or 5 generations, the populations have died out.

But I have a problem with this. It doesn’t say whether or not as each generation hatched, new ‘normal’ males were added to the cage. In the open, there would always be an influx of ‘normal’ males. So do we really want to add to the population of mosquitos? Really?
