Big and tall parents do not have more sons

In a 2005 paper Kanezawa proposed a generalisation of the classic Trivers- Willard hypothesis. It was argued that as a result taller and heavier parents should have more sons relative to daughters. Using two British cohort studies, evidence was presented which was partly consistent with the hypothesis. I analyse the relationship between an individual being male and their parents’ height and weight using one of the datasets. No evidence of any such relationship is found.
