The correct answer is: B. Diploid number
The diploid number (2n) is the number of chromosomes in a somatic cell. It is the sum of the haploid number (n) of the gametes that fused to form the zygote. In humans, the diploid number is 46 chromosomes.
The haploid number (n) is the number of chromosomes in a gamete. In humans, the haploid number is 23 chromosomes.
The triploid number (3n) is the number of chromosomes in a cell that has three sets of chromosomes. In humans, triploid cells are usually non-viable and are spontaneously aborted.
The answer to the question is B. Diploid number. The diploid number is the number of chromosomes in a somatic cell. It is the sum of the haploid number (n) of the gametes that fused to form the zygote. In humans, the diploid number is 46 chromosomes.
