How do you find the haploid number?
Under normal conditions, the haploid number is exactly half the total number of chromosomes present in the organism’s somatic cells, with one paternal and maternal copy in each chromosome pair. For diploid organisms, the monoploid number and haploid number are equal; in humans, both are equal to 23.
What is the haploid number of chromosomes when the diploid number is 12?
6 chromosomes
The haploid (n) number would be 23 chromosomes found in the gametes, reproductive cells of sperm and ova. For the organism in this example the diploid (2n) number is 12 making the haploid (n) number would be half of that or 6 chromosomes.
What is the haploid number of 18?

What is a haploid number diploid number?
In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
What is the diploid number for a human?
46 chromosomes
Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
What does 2n 12 mean?
2n=12. How many pairs of homologous chromosomes would be present in one of he nuclei at the end of telophase I of meiosis.
How do you know if a number is haploid or diploid?
Diploid cells contain two complete sets (2n) of chromosomes. Haploid cells have half the number of chromosomes (n) as diploid – i.e. a haploid cell contains only one complete set of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas.
