PLOS Genetics: Effects of cis and trans Genetic Ancestry on Gene Expression in African Americans

"...identification of variants in the Paint and Quarter Horse significantly associated with altered muscle fiber type proportions favorable for increased sprinting ability. A strong signature...was also identified in breeds that perform alternative gaits, the determination of size." This study has demonstrated the utility of this approach for studying the equine genome and is the first to show a functional consequence of selective breeding in the horse." thumbnail

Mosquito preference for human versus animal biting has genetic basis

Mosquitoes are more likely to feed on cattle than on humans if they carry a specific chromosomal rearrangement in their genome. This reduces their odds of transmitting the malaria parasite, according to a University of California, Davis, study published Sept. 15 in the journal PLOS Genetics.
