Human cells can be described by how many sets of chromosomes they carry. Almost all body cells are diploid, and only the egg and sperm cells (gametes) are haploid:
- Haploid cells
- Diploid cells
Haploid Vs Diploid
Haploid cells pertains to the number of chromosomes found in a gamete or represents half of the normal chromosome count in a particular somatic cells. The primary difference between haploid and diploid cells are the total number of chromosomes they consist of.[1]
In humans, the haploid cells are the gametes. During meiosis, the homologous chromosome pairs separate in the first division and the sister chromatids separate in the second, producing 4 haploid daughter cells.[2]
When sex cells such as egg and sperm meet, the combined genetic material creates a full 46 chromosomes becoming diploid.Thus human Sexual reproduction is designed as a natural method of producing genetically diverse offspring.[3]
