Triple X syndrome is a form of chromosomal variation characterized by the presence of an extra X chromosome in each cell of a human female. The condition occurs only in females, which have an additional chromosome, resulting in the formation of XXX.
The female may not experience severe phenotypic characteristics though because of Barr Bodies. 2 (randomly selected) of the 3 X chromosomes will be "switched off" in each cell.
What else can I help you with?
A human cell with 2 Barr bodies and no Y chromosome is from?
The human cell is most likely from a female individual. Barr bodies are inactivated X chromosomes in females, and the absence of a Y chromosome indicates that the individual does not have male sex chromosomes.
Homologous chromosomes is terms of the number of genes and the type of genes they have?
Homologous chromosomes are pairs of chromosomes (one from the female and one from the male), each of which contains genes which correspond to the genes on the other chromosome in the pair. For example, if a chromosome contains a gene for eye color, the corresponding chromosome will also have a gene for eye color in the same place.
What are the names of all the 46 chromosomes?
The word that describes similar chromosomes, one from each parent is homologous. Each human for example has, with certain exceptions 23 chromosome pairs.

Homologous chromosomes have the potential to contain exactly the same genes, but nature has made sure that they don't.
