Dendrogram from UPGMA cluster analysis of gametophyte sizes for each of days 7, 8, 9 and 10. Dimensionless scale indicates magnitude of difference between clusters. Two major clusters for each day are indicated with AL@ for cluster of large sized gametophytes and AS@ for cluster of small sized gametophytes. Specific gametophytes in each cluster for each day are identified in table 2, along with the size of each gametophyte.
