6. Can a person have more than 46 chromosomes? What would be the result if this happened?

Yes, a person can have more than 46 chromosomes. Normally, humans have 46 chromosomes, which are organized into 23 pairs. However, certain genetic disorders can cause an individual to have more than the typical number of chromosomes. For example, Down syndrome is caused by an extra copy of chromosome 21, resulting in a total of 47 chromosomes. This condition is also known as trisomy 21. Other genetic disorders that can lead to an increased number of chromosomes include Klinefelter syndrome (47,XXY) and Turner syndrome (45,X). Having an abnormal number of chromosomes can lead to various physical and developmental challenges, depending on the specific disorder.
