What is the haploid of 3n ?

Now Thats a tricky question! Thanks for asking. For odd ploidy numbers, haploid number is not easy to designate. The most common and logical definition of Haploid number is _"Haploid number is _*_half_*_ of the no. of sets of chromosomes present in the somatic cells"._ But this is not the only definition of Haploid number. Another definition is _"Haploid number is the no. of sets of chromosomes present in the gametes"._ For humans and most animals, since the gametes typically have half the no of sets of chromosomes as that of somatic cells, both definitions mean the same. i.e. no of sets of chromosomes in gametes is exactly half of the no. of sets of chromosomes in somatic cells. However, if the somatic cells of any organism contain 3 sets of chromosomes i.e. 3n, we can not simply say that haploid is 1.5n. That won't make any sense. In this case, we will go for the second ddefinition. _Haploid number in this case would be the no of sets of chromosomes present in the gametes of that organism._ So, for example, *if the somatic cells are 3n, and gametes are 1n, the haploid number would be simply 1n.* I hope that it makes sense, otherwise, please feel free to reply back.
