What does diploid refer to in terms of chromosome number?

• A. n=23
• B. 2n=46
• C. 3n=69
• D. X=1

Answer: (B)

Diploid refers to a condition in which a cell contains two complete sets of chromosomes. In humans and many other organisms, the diploid number is designated as 2n, which means there are two sets of chromosomes – one set inherited from each parent. For humans, this diploid number is 46 chromosomes, organized into 23 pairs. Thus, when considering the representation of chromosome number, 2n=46 accurately reflects the diploid state, indicating that humans possess two copies of each of the 23 chromosomes, resulting in a total of 46. This is essential for sexual reproduction as it ensures that offspring receive genetic material from both parents, maintaining genetic diversity and stability across generations.
