Suppose That a Homeotic Gene from Drosophila Is Introduced into an Arabidopsis

Multiple Choice

Suppose that a homeotic gene from Drosophila is introduced into an Arabidopsis embryo that has a pre- existing mutation in one of its homeotic flower genes. What effect would you expect and why?

A) a mixture of roughly equal numbers of Drosophila and plant gene product, producing an intermediate phenotype
B) expression of the Drosophila homeotic gene correcting the mRNA of the mutant plant
C) no effect, because Hox genes are different from MADS box genes
D) correction of the sequence in the mutant by recombination with the Drosophila gene sequence
E) rescue (or negating) of the phenotype of the mutant because the fly Hox gene supplies the missing protein
