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

Although MAP kinase is often activated in multicellular animals by RTKs or cytokine receptors, signaling from other receptors can activate MAP kinase in other eukaryotic cells. we consider the mating pathway in the yeast S. cerevisiae, a well-studied example of a MAP kinase cascade linked to G protein–coupled receptors (GPCRs). Which of the following statement is incorrect?
