Question

a pedigree is a chart the look at genetic history
false
true

Explanation:

First, correct the grammar of the statement: "A pedigree is a chart that looks at genetic history." A pedigree chart is indeed used to analyze the genetic history of a family, tracking traits (including genetic disorders) across generations. So the core idea of the statement (pedigree as a chart for genetic history) is correct, even with the initial grammar error.

Answer:

True (Note: The original statement has a grammar error ("the look" should be "that looks"), but the concept about a pedigree being a chart to examine genetic history is accurate.)
