Textbook Question

Chapter 17, Problem 11P

a.	Assume that two transcription factors are required for expression of the blue pigmentation genes in pansies. (Without the pigment, the flowers are white.) What phenotypic ratios would you expect from crossing strains heterozygous for wild-type and recessive amorphic alleles for each of the genes encoding these transcription factors?
b.	Now assume that either transcription factor is sufficient to get blue color. What phenotypic ratios would you expect from crossing the same two heterozygous strains?
