When two independent pure lines AAbb and aaBB of pea with white flowers are crossed, the F1 progeny has purple flowers. Gene A and B link at 20 map unit. The following conclusions were made
A. When an heterozygous individual of the genotype AaBb is test crossed, progenies with purple and white in a ratio of 1:3
B. When an heterozygous individual of the genotype AaBb is test crossed, progenies with purple and white in a ratio of 1:9
C. This is an example of complementary gene action
D. The F2 progeny obtained on selfing shows both pruple and white flower in a ratio of 9:7
