1 A match on the X can eliminate many ancestors from an autosomal match BUT a small match on the X can be from a different line so this is not guaranteed.  There seems to be less recombination on the X. I have heard of cases where a child got an unrecombined X from their mother. In my own family, the number of recombined segments is quite small. So it seems to me that on the female to female line the X behaves like a sluggish autosome and is not quite as actively recombined as the other chromosomes.
ANSWER: Malaria can be prevented in a number of ways, the main three of which are bite reduction, prophylaxis and vector control.Bite reduction just means steering clear of mosquitoes, and specifically those that transmit malaria.NSWER: Malaria can be prevented in a number of ways, the main three of which are bite reduction, prophylaxis and vector control.
Human malaria is caused by four different species of a parasite belonging to genus Plasmodium: Plasmodium falciparum (the most deadly), Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale.The last two are fairly uncommon. Many animals can get malaria, but human malaria does not spread to animals.alaria is caused by the protozoan parasite Plasmodium, which is carried by mosquitoes of the genus Anopheles. When the mosquito bites an infected person, it sucks in the parasites residing in the person's blood.
