Explanation:
Detailed explanation-1: -A pair of corresponding chromosomes is homozygous. The gametes of sexually reproducing organisms are haploid. If an organism’s haploid number is 6, its diploid number is 3.
Detailed explanation-2: -Hence, an organism with cells 2n=6 would be an organism that is diploid and has 6 chromosomes total. In other words, this organism has 3 pairs of chromosomes.
Detailed explanation-3: -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.
