Karyotype
A karyotype is the arrangement of all the chromosomes from an individual’s cells. A karyotype is a test used to check for chromosome abnormalities. A picture of a person’s chromosomes is created by staining the chromosomes with a special dye, photographing them through a microscope and arranging them in "homologous" pairs.
A human has 46 chromosomes in every living cell. Half are inherited from the mother, and the other half from the father. Except for the male sex chromosome Y- each chromosome each chromosome come in pairs.
Chromosomal abnormalities can be a cell that is missing a chromosome (or having an extra chromosomes), deletions or additions to the chromosme structure.
