What is a diploid organism?
The term diploid refers to a cell or an organism that has two sets of chromosomes. In humans and other higher forms of living things, one of the two sets is derived from the mother’s gamete and the other is from the father’s gamete. The chromosomes from the two gametes have come together during fertilization.
What happens when you have 47 chromosomes?
Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
How many cells are produced in mitosis and meiosis?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
