Question Overview:In this question, you are required to select the answer that represents the results of chromosomal crossover during meiosis. In order to answer this question, you must know how to express scientific information verbally and recall that crossing over occurs when chromosomes exchange segments of their genetic material.

Answer Rationale:

Option A is incorrect. If you chose option A, you probably noticed that the diagram shows that the chromosomes contain some of the paternal (father) genetic information. However, a closer look at the diagram shows that crossing over during meiosis results in two chromosomes, which are mixtures of the paternal (father) and maternal (mother) chromosomes.

Option B is incorrect. If you chose option B, you probably noticed that the diagram shows that the chromosomes contain some of the maternal (mother) genetic information. However, a closer look at the diagram shows that crossing over during meiosis results in two chromosomes, which are mixtures of the paternal (father) and maternal (mother) chromosomes.

Option C is correct. If you chose option C, you noticed that the diagram shows that crossing over during meiosis results in two chromosomes which are genetic combinations of both the maternal (mother) and paternal (father) chromosomes.

Option 0 is incorrect. If you chose option D, you probably noticed that the diagram shows that the chromosomes contain a combination of the genetic information from the parent chromosomes. However, a closer look at the diagram shows that the chromosomes not only contain a combination of the parent's genetic information, they also contain the same amount of genetic information as the parents.
