In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that the allels of two genes are segregating independently. Explanation: The 9:3:3:1 ratio observed in a dihybrid cross denotes that the alleles of two different genes are assorting independently of each other during gamete formation. This classic Mendelian dihybrid ratio demonstrates the law of independent assortment, which states that gene pairs located on different chromosomes segregate independently during meiosis, resulting in this phenotypic ratio in the F2 generation. Thus, each trait is inherited independently, producing four distinct phenotype classes in the ratio of 9 (both dominant traits) : 3 (dominant first, recessive second) : 3 (recessive first, dominant second) : 1 (both recessive).
