"If the haploid number for a species is 3, each dividing diploid cell will have how many chromatids at metaphase?"
The answer is 12... I thought it was 3. What is haploid and what is diploid??

haploid is half the number of chromosomes, diploid is full
so the cell would normally have 6
however, since it is dividing it has double the genetic material so that both of the new cells have all of the genetic material- thus the dividing cell has 12

The haploid number is the number of chromosomes in a gamete of an individual.
Diploid cells have two identical copies of each chromosome

a chromosome has 2 chromatids

if the haploid number is 3 you multiply it by 2 and get the diploid number of 6

6 x 2=12

any cells having 1 set of chromosomes, they're called haploid. Example: gonad cells.
Those having 2 sets of chromosomes are diploid cells.
A species with haploid num=3 means, each of its cells has 3x2=6 sets of chromosomes.
At cell division, each chromosome split into 2 chromatids. thus, the answer is 12 SET.

haploid cells are also call gametes (sex cells) and can be represented as "n". during meiosis the diploid cells divides again so that the offspring of the gametes will be diploid. diploid cells can be represented as "2n" living cells have to produce haplod cells that way when they reporduce with other haplid cells u will wind up with a diploid cell. like n+n=2n. with no haploid cells offspring will be 4n causing mutation
