Genebanks house over 7 million accessions representing vast allelic diversity that is a resource for sustainable breeding. Discovery of DNA variations is an important step in the efficient use of these resources. While technologies have improved … WebThe assumptions on the means are the same as that of the ANOVA; that is, they are assumed to be from normally distributed populations with common variance . The grand mean is , and the pooled estimate of the common but unknown variance is. Note that the pooled estimate of the variance is identical to MSW in the ANOVA.
