The data about leg size in the parental generation is NOT found here, but it is expected that it is a quantitative trait.
<h3>What are quantitative traits?</h3>
Quantitative traits are phenotypic features associated with the inheritance of many genes, the infection among them and the environment.
Leg size, height, and weight are quantitative traits because there are many genes involved in their expression patterns.
Both quantitative and qualitative (monogenic) traits are selected in the natural populations via natural selection.
In conclusion, it is expected that leg size is a quantitative trait.
