The cluster analysis method of karyotype resemblance-near coefficient was used to study the relationship and evolution of seven species in the genus Kerria.
Additionally, a karyotype can be done to look for chromosomal abnormalities and specific genetic tests can be ordered if there's a family history of Fragile-X syndrome.
The next most common scenario is mosaicism, meaning the individuals have some cells in their body with the 45, X karyotype and others with a 46, XX karyotype.
Just how many of these abnormalities linked with Turner syndrome are actually present depends on the proportion of cells the person has with the 45, X karyotype.
Most commonly, an entire X chromosome is missing, giving a 45, X karyotype - in other words, the person only has 45 chromosomes, missing one of the X chromosomes.
