Detailed explanation-1: -Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs.

Detailed explanation-2: -In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad. In humans, 2n = 46, and n = 23.

Detailed explanation-3: -Complete answer: The ‘2n’ stage represents the diploid stage. During this condition, two sets of chromosomes are present within one cell. In almost all human cells, that is somatic cells the diploidy results in 46 chromosomes in 23 pairs. Diploid cells possess two copies of genes as a result of two sets of chromosomes.

Detailed explanation-4: -Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.

Detailed explanation-5: -Haploid. A haploid cell has only a single set of chromosomes. Most cells in humans are diploid rather than haploid, meaning they have two copies of each chromosome.
