Human karyotypes for teaching: (46,XY, normal male) These karyotypes are from a normal male. There is a full set of 23 homologous pairs, including the X and Y. These karyotypes are from the Wisconsin State Laboratory of Hygiene. They are intended for use in teaching to help students study human chromosomes. Copyright for these images remains with the State Laboratory of Hygiene, apply to them for permission for any other use than non-profit teaching. Each karyotype is available in one of three forms: The original unmodified smear. These may have extra material, and often have some chromosomes crossed, which makes them less useful for a class exercise in which students cut apart and arrange the individual chromosomes. A copy of the original, with extraneous materials removed, crossed chromosomes separated, and all chromosomes separated slightly to faciliate cutting apart of the chromosomes in a printed copy. This form is intended for student use in an introductory biology class. A "key", with the chromosomes arranged in standard order.
