FINDING SUPPORTING DETAILS
A detail is a piece of information. Supporting details are the facts and examples that a writer presents to back up the main idea of a paragraph or a section.
1. Read Section 6.4 on pages 142–145. Find at least three examples that support the main idea: While a recessive allele that can produce a genetic disorder does not affect a carrier's health, a carrier can pass the recessive allele on to an offspring.
Write the examples in the left column of the chart. In the right column, create a who, what, when, where, why, or how question about the example. You can use the same example more than once as you write your questions. The first one has been done for you.
