They clog arteries and inhibit proper blood flow. The gene for sickle-cell anemia is recessive.&lt;br /&gt;•  Phenylketonuria (PKU) is an inherited disease caused by a recessive gene. People with this disease are missing an enzyme that is needed to break down the amino acid phenylalanine. Many foods contain this amino acid.&lt;br /&gt;•  Tay-sachs disease and Huntington’s disease are also inherited diseases.&lt;br /&gt;&lt;br /&gt;3–11   How does the environment affect inherited traits?&lt;br /&gt;OBJECTIVE: Explain how the living conditions of an organism affect the way it develops.&lt;br /&gt;Key Terms&lt;br /&gt;mutagen: substance that increases the rate of mutation&lt;br /&gt;carcinogen: substance that causes cancer&lt;br /&gt;Lesson Summary&lt;br /&gt;•  The environment can change the way a trait is expressed.&lt;br /&gt;•  Heavy winds can cause trees to bend as they grow. Poor soil can cause plants to grow smaller than normal. These are environmental influences.&lt;br /&gt;•  The environment can cause mutations in genes.&lt;br /&gt;•  Mutations are changes in the genetic material of an organism. Some mutations are harmful to the organism; some are beneficial.&lt;br /&gt;•  Mutations are usually not passed on to offspring if they occur only in the body cells.&lt;br /&gt;•  Mutagens are factors that increase the likelihood of mutations.&lt;br /&gt;•  Ultraviolet light rays, chemicals in water, and radiation are all mutagens.&lt;br /&gt;&lt;br /&gt;3–12   How is genetics used to improve living things?&lt;br /&gt;OBJECTIVE: Explain the different methods of controlled breeding.&lt;br /&gt;Key Terms&lt;br /&gt;controlled breeding: mating organisms to produce offspring with certain traits&lt;br /&gt;mass selection: crossing plants with desirable traits&lt;br /&gt;hybridization (hy-brihd-ih-ZAY-shuhn): mating two different kinds of organisms&lt;br /&gt;inbreeding: mating closely related organisms&lt;br /&gt;Lesson Summary&lt;br /&gt;•  Mating organisms to produce offspring with certain traits is called controlled breeding.&lt;br /&gt;•  Mass selection involves crossing plants with desirable traits. This takes several generations of using only the plants that have the desirable trait.&lt;br /&gt;•  The mating of two different kinds of organisms is called hybridization. The offspring show traits of both parents.&lt;br /&gt;•  Inbreeding is the mating of closely related organisms.
