It is many years since I read any publications from Britten and Davidson.
However, you cannot use the quantity of DNA, as nucleotide pairs per haploid
cell, as a measure of "genetic information". This is because of the vast
amount of DNA that is non-coding (though not always with no function,
structural or otherwise). In 1969, this picture was not obvious, although the
research areas B & D worked in *were* the various classes of repetitive DNA.
