ANTONII [103]

Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.

Explanation:

The 9:3:3:1  ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.

Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.

However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.
