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 transmitted by different Anopheles species, depending on the region and the environment. Anophelines that can transmit malaria are found not only in malaria-endemic areas, but also in areas where malaria has been eliminated. The latter areas are thus constantly at risk of re-introduction of the disease.arvae of Anopheles mosquitoes have been found in fresh-or salt-water marshes, mangrove swamps, rice fields, grassy ditches, the edges of streams and rivers, and small, temporary rain pools. Many species prefer habitats with vegetation. Others prefer habitats that have none.
