A large genetic variability, previously undetected, has been found in the vector responsible for Chagas disease, says a study.
... size and sex-specific migration were all discounted as contributors to the observed patterns of genetic variability. Only the process of polygyny could by itself account for the sex ratio skew and ...
... decreases the danger of endogamy (mating among relatives) and increases the genetic variability of offspring. Genetic variability is known to be an advantage for offspring, and the MHC effect could be ...
... that developing a broadly protective vaccine for malaria may be challenging because the parasite's genetic makeup is so variable, constantly changing. If a vaccine targets only a single protein in the ...

The study results point out the need for further investigation into the genetic variability of different ethnic groups. In addition to previously identified, clinically ...
... a serious drop in numbers and decreases in population size may be reflected in decreases in genetic variability.
This can compromise the adaptive potential of the populations for the future and ...
Women have been more successful on average in passing their genes on to the next generation. 'This is because a few males have fathered children with multiple females, which occurs at the expense of ...

Venezuelan scientists have shown that although HIV/AIDS subtype B is still predominant in the Americas, other variants have been increasing in frequency.
... of Neanderthals by studying the genetic structure of the mitochondrial DNA (mtDNA) and by analyzing the genetic variability, modeling different scenarios. The study was possible thanks to the ...
