| None of the fixation indices for polymorphic loci in either species were significantly negative. |
| This is because a single locus does not define the polygenic trait, but rather it is the net effect over multiple loci, which defines the trait. |
| Quantitative trait loci analyses have recently been initiated to map some of these polygenically controlled traits. |
| The first addresses the question of how to preserve, respect or regenerate genius loci under fast changing conditions. |
| The genes may be groups of multiple genes at different loci or sets of multiple alleles at the same locus. |
| However, few studies have examined intraspecific diversity at individual resistance loci. |
