A46 in humans and 46 in flies
B23 in humans and four in flies
C23 in humans and eight in flies
D46 in humans and eight in flies
Answer & Solution
Correct answer: D. 46 in humans and eight in flies
1. Every eukaryotic species has a specific chromosome number in the nuclei of its body cells.
2. For humans that number is 46.
3. For fruit flies that number is eight.
4. The pairing 23 and four halves both figures, which describes gametes rather than body cells.
5. The correct pairing is 46 and eight.
