In this problem, students are asked to determine if all the different-color kittens in a litter could be related to the same father. The challenge to students is to use cat coat color genetics to determine if all of the kittens in a litter could have had the same father. The set of traits seen in cat coat color will allow students to practice analyzing pedigrees that show traits within a family. By looking at the characteristics of offspring and using patterns of inheritance, students can infer the genotypes of parents. A materials list, teacher background information, safety practices, references, assessment, and outcomes are provided. This book selection includes the Table of Contents, Preface, Catalog of Problems, Acknowledgments, About the Authors, References, and Index.
