Male XY karyotype

X and Y karyotype with G-banding labelling. Note the difference in overall size of the 2 sex chromosomes.

G-banding - chromosome banding pattern seen by trypsin treatment and then staining with the dye Giemsa stain.

Metaphase is a cell division term referring to the third mitotic stage, mitotic spindle kinetochore microtubules align chromosomes in one midpoint plane. Metaphase ends when sister kinetochores separate. Originally based on light microscopy of living cells and electron microscopy of fixed and stained cells. A light microscope analysis called a "metaphase spread" was originally used to detect chromosomal abnormalities in cells.
