From: Genetic linkage map construction and QTL identification of juvenile growth traits in Torreya grandis
( A) Age-dependent expression profiles of two different genotypes at the QTL detected in different linkage groups for stem diameter and height QTLs in Torreya grandis cv. Merrilli . Solid and broken curves represent QTL genotypes QQ and Qq, respectively. (B) Age-dependent genetic effects of the QTLs detected on stem diameter and height growth. The genetic effects are estimated as the differences of genotype QQ minus Qq.
