Question
- A. XY
- B. XX
- C. YY
- D. XZ
Answer
The correct option is XX. This answer is correct because it matches the approved learning objective to describe females as having XX sex chromosomes in the subtopic Sex determination.
Explanation
The correct option is XX. XX is correct because it directly supports the approved learning objective to describe females as having XX sex chromosomes. This belongs to the subtopic Sex determination within Reproduction, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Sex determination.
Common mistake
Misunderstanding Female Chromosomes
Students often confuse the sex chromosomes of females, mistakenly stating that they have XY chromosomes instead of XX.
Remember that females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). Visual aids or diagrams can help reinforce this distinction.
