The phenomena of polygenic inheritance would have become a grievous fault to his investigation, if he had investigated human height instead of stem length of pea plants.

Explanation:

The polygenic or polygenetic inheritance is the inheritance where the trait of a particular allele is passed on to the next generation with many genes involved in order to show the genotype and phenotype of the allele present on the same chromosome.

The stem length or plant height depends on the single factor of allelic gene inheritance and expression in phenotype, making it simpler to trace down the division of meiosis and control the experiment as needed. Considering human height for a chance, may lead to uncontrolled condition of having next generation study as well as the time required to be long. Other factor was that the height is dependent not only on the height gene expression but is controlled by nutrition and environmental factors too.
