The average net improvement of bite opening was 2.6 mm, mainly due to extrusion of mandibular and maxillary molars.
The "net improvement" statistic (NI)=maximum [(I1×Iw-I1xI2)/2, (I2×Iw-I1×I2)/2] estimates the number of loci where favorable alleles can be gained minus the number of loci where favorable alleles can be lost in the single cross.
A "net improvement" (NI) statistic, which estimates the relative number of favorable alleles that can be gained from Pyminus the relative number of favorable alleles that can be lost from I1 or I2, is presented.
The continuum model utilized here represents a net improvement above such models utilized in other works.
