    Mamm Genome 18:240-5. 2007
    ..This result underlines the possibility that seemingly pleiotropic effects of QTLs may frequently be due to linked loci and that high-resolution mapping will often be required to distinguish between pleiotropy and linkage...

    Curr Biol 15:R19-21. 2005
    ..Identifying genes that influence phenotypic variation is extremely difficult, especially when the allelic variants only have a small effect. A recent study has used a novel approach to identify a gene that affects the behaviour of mice...
