From the Jacket
To this treatise was concerned with the genetic and biometric foundations on which population genetics must be built. Since the emphasis here is to be on higher organisms, most emphasis will be placed on diploids, but some attention must be given to the haploid phase, toe sex-linked loci, and to polysomic loci and polyploids.
