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.
If there are any general principles that may be inferred for health planners wishing to conduct iron interventions in malaria-endemic areas, they are the following: 1) beware populations with potentially compromised immunity (especially to malaria), for example, HIV carriers, primigravidae and young infants; 2) beware high dose supplementation; 3) beware supplementation during the peak malaria transmission season; 4) beware known AS and SS genotypes; 4) beware interpreting low population ...
