Figure 5

The number of HeT-A and TART elements per genome are correlated in D. melanogaster stocks, cells and tissue types. This figure shows data for a cultured cell line (S2), for diploid cells and for polytene salivary gland cells from four stocks (Oregon R, 2057, Su(var) 2054 and G3). When analyzed, the data show that the number of the two elements present are linearly correlated at better than the 95% confidence level when polytene salivary gland measurements are compared, when diploid cell measurements are compared, or when all data is pooled and compared.31 The solid black line is the best linear fit to the data, the dotted line is the best quadratic fit. If the data point in the extreme right-hand upper corner is omitted from the analysis, the best linear fit for the remaining data is indistinguishable from the quadratic fit at the level of detail in this plot.
