Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
The answer is C. The others have just one dominant and recessive allele.
Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)
Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to
contribute… then the rest works out as follows:
b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett
squares.

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore
only has the dominant A and dominant B alleles – no recessive allele possible.
