In which one of the following, complementary gene interaction rato of $9: 7$ is observed?

Fruit shape in Shepherd's purse

Coat colour in mouse

Feather colour in fowl

Flower colour in pea

Solution

W Bateson and R C Punnett observed complementary gene interaction for flower colour in sweet pea (Lathyrusodoratus). In complementary interaction, two separate pairs of genes interact to produce the phenotype in such a way that neither of the dominant genes is expressive unless the other one is present. In $F_{2}$ generation, complementary genes produce a ratio of $9: 7$
