Summary
The belief that sex-linkage is unimportant in quantitative inheritance is not based on evidence.
The conditions necessary for discriminating between the alternative hypothesis that sex-linkage is, or is not, negligible in quantitative traits, are discussed.
Examples from the literature are cited to show that the evidence is by no means all in favour of the negligible sex-linkage alternative.
It is recommended that this matter be investigated further. It seems unwise to ignore sex-linkage in quantitative inheritance without further testing.
