Explain how the terms diploid and haploid relate to human chromosome number in both autosomes and sex cells
What will be an ideal response?
Humans have 46 chromosomes that exist in pairs, with most cells having 23 homologous pairs, or 46 chromosomes. This is the diploid, or 2n, number of chromosomes. One member of each homologous pair is contributed by each parent. Certain cells, such as eggs and sperm (gametes), contain only one copy of each chromosome. These cells have 23 chromosomes, which is the haploid, or n, number of chromosomes.
