Question
Chapter 17.2, Problem 1C
Summary Introduction
To describe: The relative merits of Drosophila melanogaster, Caenorhabditis elegans, Mus musculus, and Arabidopsis thaliana those have made these organisms valuable models in developmental genetics.
Introduction: The growth and development of an organism is controlled by genes. Developmental genetics gives us insight on how these genes influence the growth and development of an organism. The patterns of morphogenesis in different species are investigated. Information necessary to build an organism is passed in the form of genes from one generation to the next.
