Question

The following is the biochemical pathway for purple pigment production in flowers of sweet pea:
Colorless precursor 1 →AlleleA Colorless precursor 2 →AlleleB Purple pigments
Recessive mutation of either gene A or B leads to the formation of white flowers. A cross is made between two parents with the genotype: AaBb × aabb. Considering that the two genes are not linked, the phenotypes of the expected progenies are
A) 9 purple : 7 white
B) 3 white : 1 purple
C) 1 purple : 1 white
D) 9 purple : 6 light purple : 1 white
