Link?

I am far from an expert on this, but I believe a Karyotype is a dye and photograph (hence the suffix "otype") method of counting and identifying chromosome chains. The XX/XY etc. depictions shown in the chart are a method of representing individual sex chromosome or chromosome pairing for identifying sex of the individual within a species (such as human).

In any case, although there may be outliers in the natural occurrence of chromosomal pairs in the human species the vast majority are XX or XY in roughly even amounts. The frequency of outliers within the population seems to be still up for debate as I've seen different "experts" offering different numbers from way less than 1%, as shown in your chart, to over 1%. You'd think "experts", which I am not one of, would be able to get their act together on this so the rest of us can move along on this topic. Then there's the programming or psychological angle where XX thinks she's Napoleon and XY thinks he's Josephine. For all that I'll stick with the two bucks and counterfeits until the "experts" finally straighten it all out for the rest of us.

Thank you for the chart, lrshultis, as I haven't seen that one before.

Will do :)

YES! LOL!
