Question
Chapter 36.2, Problem 1CS
Summary Introduction
To determine: The way in which the animal body polarity is similar to the polarity of plants.
Introduction: Mouse chromosomes have Hox genes which are arranged based on the colinearity rule. These gens regulate the pattern of expression of morphological features from the anterior to the posterior end.

Dominguez et al. (2004) suggest that by studying genes that determine growth and tissue specification in the eye of Drosophila, much can be learned about human eye development. (a) What evidence suggests that genetic eye determinants in Drosophila are also found in humans? Include a discussion of orthologous genes in your answer. (b) What evidence indicates that the eyeless gene is part of a developmental network? (c) Are genetic networks likely to specify developmental processes in general? Explain fully and provide an example.
