Vedclass · Answer

(C) The $9:7$ phenotypic ratio is a modification of the typical Mendelian dihybrid ratio $(9:3:3:1)$.This ratio occurs due to complementary gene interaction.In this interaction,two independent pairs of genes interact to produce a single trait,and the presence of both dominant alleles is required for the expression of the phenotype.If either gene is present in a homozygous recessive state,the phenotype is not expressed,resulting in the $9:7$ ratio.

The ratio of $9:7$ is obtained as a result of:
