jennifer agrees that a sample of her dna may be used in a scientific study. the scientists will analyze the sample and compare it with information in data bases. based on this analysis, which of the following information about jennifer could the scientists be able to determine? select all of the answers that apply.
a. her ethnic background or heritage
b. her exact age, weight, and height
c. her chances of developing certain diseases

Explanation:

To determine the correct options, we analyze each:

• Option A: DNA analysis can reveal ethnic background/heritage as certain genetic markers are associated with ethnic groups.
• Option B: Exact age, weight, height are not determined by DNA analysis (these are phenotypic traits influenced by multiple factors, not directly from DNA).
• Option C: DNA analysis can show genetic predispositions to certain diseases (e.g., BRCA genes for breast cancer).

So, A and C are correct as they relate to information derivable from DNA analysis.

Answer:

A. her ethnic background or heritage
C. her chances of developing certain diseases
