Genetics: Analysis and Principles 4th Edition by Robert Brooker

Exercise 12

Though we often think of genes in terms of the phenotypes they produce (e.g., curly leaves, flaky tail, brown eyes), the molecular function of most genes is to encode proteins. Many cellular proteins function as enzymes. The following table describes the map distances between six different genes that encode six different enzymes: Ada , adenosine deaminase; Hao - 1 , hydroxyacid oxidase-1; Hdc ,histidine decarboxylase; Odc - 2 , ornithine decarboxylase-2; Sdh - 1 , sorbitol dehydrogenase-1; and Ass - 1, arginosuccinate synthetase-1.
Map distances between two genes:
Construct a genetic map that describes the locations of all six genes.
