Chapter 11
Introduction to Genetics

In this chapter, students will read about the principles of genetics and probability that determine how biological traits are inherited. They will also read about the process of meiosis and its importance in genetics.. The links below lead to additional resources to help you with this chapter. These include Hot Links to Web sites related to the topics in this chapter, the Take It to the Net activities referred to in your textbook, a Self-Test you can use to test your knowledge of this chapter, and Teaching Links that instructors may find useful for their students.

Section 11-1: The Work of Gregor Mendel
The principle of dominance states that some alleles are dominant and others are recessive.
When each F1 plant flowers, the two alleles are segregated from each other so that each gamete carries only a single copy of each gene. Therefore, each F1 plant produces two types of gametes—those with the allele for tallness and those with the allele for shortness.

Section 11-2: Probability and Punnett Squares
The principles of probability can be used to predict the outcomes of genetic crosses.

Section 11-3: Exploring Mendelian Genetics
The principle of independent assortment states that genes for different traits can segregate independently during the formation of gametes.
Some alleles are neither dominant nor recessive, and many traits are controlled by multiple alleles or multiple genes.

Section 11-4: Meiosis
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells.

Section 11-5: Linkage and Gene Maps
The chromosomes assort independently; individual genes do not.

Mendelian Genetics
A tutorial with problem sets, excellent graphics, and explanations of some of the most important principles of Mendelian genetics.
