Walden University BIOL1001 WEEK 4 EXAM. Questions and Answers
(Graded A).
Question 1
How could two parents with curly hair (a dominant condition) have boys and girls with straight
hair (a recessive condition)?
Answer: D. The recessive condition could happen if both parents were heterozygous carriers of
the recessive allele.
Question 2
What is the role of fossils in supporting the theory of common descent?
Answer: C. There have been many fossils of intermediate types discovered that provide strong
support for the theory of common descent.
Question 3
If a blue-colored flower crossed with a white-colored flower produced light blue-colored flower
offspring, then it’s most likely a case of:
Answer: A. Incomplete dominance
Question 4
DNA is often likened to an instruction manual. According to this analogy, the typographical
errors that would inevitably result when the DNA “manual” is transcribed would be similar to:
Answer: D. Mutations
Question 5
Match each model of life on earth in column 1 with its description in column 2.
Question Correct Match
Static Model B. Species arise separately and do not change over time.
