Is having 47 chromosomes bad?
Males with XYY syndrome have 47 chromosomes, two of which are Y chromosomes. Most cases of XYY syndrome are due to a cell division error in the sperm prior to conception. Rarely, the cell division error occurs after conception resulting in a mosiac of cells with 46 chromosomes and 47 chromosomes.
What if a human has 48 chromosomes?
48,XXYY syndrome is a chromosomal condition that causes infertility, developmental and behavioral disorders, and other health problems in males. 48,XXYY disrupts male sexual development.
What happens if you have less than 46 chromosomes?
A gain or loss in the number of chromosomes from the normal 46 is called aneuploidy. A common form of aneuploidy is trisomy, or the presence of an extra chromosome in cells. Tri- is Greek for three; people with trisomy have three copies of a particular chromosome in cells instead of the normal two copies.
What happens if a human has 45 chromosomes?
There are 2 types of Turner syndrome: monosomy X TS and mosaic TS. About half of all girls with Turner syndrome have a monosomy disorder. Monosomy means that a person is missing one chromosome in the pair. Instead of 46 chromosomes, the person has only 45 chromosomes.
