Complete Set of Chromosomes

Complete set of chromosomes

**The complete (diploid) set** consists of two identical halves (in a diploid cell there are two identical sets). In this case, the nucleus has two centrioles and two spindles. Thus, to divide a unicellular organism, one such cell is required. To obtain a complete (diploid) set of DNA, a process called meiosis or mitosis is needed. ** *How does the process of formation of a complete (diploid) set occur?* In this case, we first have two initial cells (a single-celled organism). The organism then undergoes a process of indirect division, which results in the formation of one new whole single-celled individual. During meiosis, somatic cell division occurs. For example, when a zygote is formed from two germ cells, four mature germ cells are formed, each of which contains a complete (diploid). During mitosis, daughter cells will also have a complete (diploid) set.

*Why is a diploid cell useful?* In many organisms, reduction division of germ cells takes place
