QTL location is indicated only by looking at which markers give the greatest differences between genotype group averages, and the apparent QTL effect at a marker will be smaller than the true QTL effect as a result of recombination between the marker and the QTL.
A localización QTL indícase só observando que marcadores dá as maiores diferenzas entre as medias dos grupos xenotípicos, e o efecto QTL aparente nun marcador será menor que o verdadeiro efecto QTL como resultado da recombinación entre o marcador e o QTL.
