NEET BIOLOGY

Detailed explanation-1: -Most mammals are diploid, like humans, but some organisms are polyploid, meaning they have more than two sets of each chromosome. For example, your standard grocery store strawberry is octoploid, with eight complete sets of seven chromosomes each, or 56 chromosomes in total, if you do the math.

Detailed explanation-2: -Ploidy can be assessed by chromosome number or flow cytometry using the DNA index (DI), the ratio of fluorescence in leukemic blasts compared with normal cells. Normal diploid cells have 46 chromosomes and a DI of 1.0, hyperdiploid cells have higher values, and hypodiploid cells have lower values.

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.

Detailed explanation-4: -Ploidy is the number of the set of chromosomes. Based on this set of chromosomes present, we have haploid, diploid, tetrad etc. Haploids have one set of chromosomes that is 23 chromosomes. Diploid has 23 pairs of chromosomes, that is, 46 chromosomes.
