Comparative Analysis of Context-Dependent Mutagenesis in Humans and Fruit Flies

Table 3

Over- and underrepresentation of genomic frequencies for several words in H. sapiens and D. melanogaster. Data is taken from a previous study [20] supplementary table (available at http://mouse.genebee.msu.ru/words/Supple3(contrast_k).xls). The numbers represent the value = [(Obs ( ) – Exp ( ))/Exp ( )]   100%, where Obs ( ) is the observed word frequency and Exp ( ) is the expected word frequency (based on the frequencies of all of its subwords).
