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.
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. In 2016, there were an estimated 216 million cases of malaria in 91 countries, an increase of 5 million cases over 2015.
