Drosophila and Arabidopsis use different sets of nonhomologous master regulatory genes to establish the body axis and specify the identity of structures along such an axis.

Question

Quizplus · Accepted Answer

Drosophila and Arabidopsis are two different organisms with distinct genetic and developmental mechanisms. While both rely on master regulatory genes to establish the body axis and specify structures along it, these master regulatory genes are not homologous between the two species, meaning that they do not share a common evolutionary origin. Therefore, they use different sets of nonhomologous master regulatory genes to achieve these developmental outcomes.
