What is the diploid chromosome number of domestic cattle?
Correct answer: B. 60
- A. 54
- B. 60
- C. 64
- D. 78
Explanation
Domestic cattle have a diploid chromosome number of 60, arranged in 30 pairs. Sheep have 54 and horses have 64 chromosomes, making them common distractors in livestock genetics questions.
