Abstract

Early quantitative genetic studies of mammalian growth had indicated that postnatal growth occurred in at least three phases (see Figure 1 ; Atchley and Rutledge, 1980 ; Atchley et al., 1984 ; Riska et al., 1985), an early phase lasting until 3 or 4 weeks in mice during which growth rate increases, a later, decelerating growth phase, lasting to about 10 weeks in mice or the time of epiphyseal fusion, and, after skeletal growth is complete, a third phase due primarily to the addition of fat to the tissues. Here we review the evidence for individual quantitative trait loci (QTLs) affecting growth during these three phases in the intercross of LG/J and SM/J mouse strains
