Fig. 3From: Dearth of polymorphism associated with a sustained response to selection for flowering time in maizeDifferenciation among families as revealed by markers during the 7 first generations of selection. Linear Discriminant Analysis using families as discriminant factor. Progenitors (upper panels) and markers’ contribution (lower panels) are represented in a F252 DSE. b MBS DSE for the first two discriminant axes. Each datapoint represents a single progenitor. For the markers, the type of polymorphism (sequence, methylation, or sequence polymorphism within a methylated region) is indicated. Only markers significantly associated with phenotypic variation are namedBack to article page
