Answer:
In summary, the 9:3:3:1 dihybrid ratio is produced because the mutations are in two parallel biochemical pathways. Generally, interacting genes in two different pathways produce an F2 with four phenotypes corresponding to the four possible genotypic classes, as in the snake example.

This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort independently into gametes.

Answer:
9:3:3:1 is the phenotypic ratio obtained in the F2 generation of a dihybrid cross.
Where the values 9 and 1 represent parental phenotypes, the other two values represent new combination. This is because of independent assortment of alleles belonging to the characters considered in the cross.
