Since its inception, Introduction to Genetic Analysis has been known for its prominent authorship—leading scientists in their field who are great educators. This market best-seller exposes students to the landmark experiments in genetics, teaching students how to analyze experimental data and how to draw their own conclusions based on scientific thinking while teaching students how to think like geneticists.

DNA homology is often striking; for example, the DNA and amino acid sequence of the gene for the electron-transport-protein cytochrome c is homologous across the range of organisms on the planet, spanning bacteria, fungi, worms, insects, mammals, and so on (Figure 1-18). This type of revelation, together with the demonstration of great homology of the biochemical processes at work in cells, has led to a new awareness that humans are indeed “cousins” to all the life-forms on Earth. Genetics has

1 2 SH 1 4  This analysis of the fly mutant identifies a gene that is part of a subset of genes that, in wild-type form, are crucial for the normal development of a wing. Such a result is the starting point of further studies that would focus on the precise developmental and cellular ways in which the growth of the wing is arrested, which, once identified, reveal the time of action of the wild-type allele in the course of development. A gene for hyphal branching A hyperbranching fungal

Index to Model Organisms, on the endpapers at the back of the book, provides chapter-by-chapter page references to discussions of specific organisms in the text, enabling instructors and students to easily find and assemble comparative information across organisms. Problem Sets No matter how clear the exposition, deep understanding requires the student to personally engage with the material. Hence our efforts to encourage student problem solving. Building on its focus on genetic analysis, the

Independent Assortment This type of breeding has been applied to many other crop species. The colorful and diverse pure lines of tomatoes used in commerce are shown in Figure 3-5. Note that, in general when a multiple heterozygote is selfed, a range of different homozygotes is produced. For example, from A/a;B/b;C/c, there are two homozygotes for each gene pair (that is, for the first gene, the homozygotes are A/A and a/a), and so there are 23  8 different homozygotes possible: A/A;b/b;C/c, and
