1. Multifactorial Traits

Traits and genetic disorders are influenced in one way or another by the environment. On the other hand, the heritability of a disorder examines the variations in multifactorial traits due to genetics in a particular population and focuses on the genetic component of variations seen in a trait.

Select a genetic disorder caused by a single-gene trait that is multifactorial. Explain how your chosen genetic disorder is influenced by the environment.

Select two diseases-one with high heritability and one with low heritability-and describe the genetic components of the diseases. In your opinion, do the individuals who inherit these diseases have a high mortality, or death, rate? Why?

2. Autism

Autism has been widely debated and discussed in recent years. Many researchers argue that autism is a genetic disorder, while others debate that autism is a result of environmental influences.

Rates of autism have been on the rise in the United States since 1990. Do these findings support the claim that the disease has a genetic basis? If so, how? If not, why not?

Can environmental influences explain these findings? Why or why not?
