- Gene crossing either A+/T+ or T+/A+ boundary have been omitted from the sample. Genes on a T+ segment are with the flow of the bias and those on an A+ segment are against the flow. For an individual gene the variable in column 5 is the product of the variables in columns 3 and 4. Columns 4 and 5 are in arbitrary linear units. Genes with the flow of the bias have a higher probability of being expressed (column 3) than those against the flow, but their level of expression when expressed is smaller (column 4). Genes against the flow are much shorter than those with the flow (column 6). The differences between the segment types are statistically significant for columns 3 and 4 using a two-tailed t-test, p values ~ 2.10-16 and 9.10-7 respectively. The difference between the segment types in column 5 is not statistically significant.
