If the diploid chromosome number of a species is 24, then a cell with 12 chromosomes would be 1)a zygote
2)a haploid cell
3)a polypoid cell
4)a diploid cell

2) a haploid cell

Explanation:

the diploid number is always double the haploid and the haploid is always half the diploid, if 12 is half of 24 then it would have to be a haploid
