The law of independent assortment.


From the genotypic ratio, it was clear that each gene was inherited independently of the other.

However he got lucky as the genes he studied didn't have linkage. If they did, the law wouldn't hold true. This was proved by the experiments of Morgan on fruit flies where more progeny had parental genes than recombinant.
