Washington Nov 28: According to a study published in the journal Science out of 450 of mosquitoes in the Anopheles genus only 60 are capable of transmitting the Plasmodium parasite in humans to cause malaria. A key finding of the study suggests that the mosquito Anopheles gambiae the most dangerous mosquitoes of the genus has the ability to increase its transmission capabilities by swapping some genes at the chromosome level. 'We found that complete intermixing can be prevented if there are multiple rearrangements on the sex chromosome. Also the traits that enhance the mosquitoes' malaria transmission capabilities can cross species
