NEET BIOLOGY

Detailed explanation-1: -The fusion of two haploid sex cells results in the formation of a diploid cell called a zygote. What is a diploid cell? A diploid cell is a cell that contains a diploid chromosome number, meaning the cell has two sets (or two copies) of homologous chromosomes in the nucleus.

Detailed explanation-2: -Most animals and plants are diploid, containing two sets of chromosomes; in each somatic cell (the non-reproductive cells of a multicellular organism), the nucleus contains two copies of each chromosome that are referred to as homologous chromosomes.

Detailed explanation-3: -From The School of Biomedical Sciences Wiki. Diploid cells, or somatic cells, contain two complete copies of each chromosome within the cell nucleus. The two copies of one chromosome pair up and are called homologous chromosomes.

Detailed explanation-4: -Examples of haploid cells are gametes (male or female germ cells). Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells.
