Final answer:
The haploid number, represented by N or 1N, is half of the diploid number (2N), which in this case equals 4.
Step-by-step explanation:
In the context of the question, 2N=4X=8, is a representation of the diploid number of chromosomes in a cell. The diploid number, denoted as 2N, is the total number of chromosomes that a cell contains. In this case, it equals 8. A haploid number, on the other hand, is the number of chromosomes in a gamete (egg or sperm cells); this is represented by N or 1N. The haploid number is always half of the diploid number because it results from a process called meiosis where the diploid cell divides to form four haploid daughter cells. Therefore, in this case, the haploid number would be half of 8, which equals 4.
