Abstract

Phenotypes on the map The connection between genes (genotype) and the adult form of an organism (phenotype) is not a simple matter of one-to-one mapping. The nonlinear process of development intervenes, dependent on various genetic inputs and interactions between cells. Using a well studied system, the mammalian tooth, Isaac Salazar-Ciudad and Jukka Jernvall have developed a computational model to bridge the gap between genotype and phenotype. Based on data from seal teeth, which show extensive morphological variation, they find that a much of the dental variation can be explained by changes in single model parameters. This work could be a step towards understanding the contribution of genes and development to variation and, therefore, to evolution.
