So here is my dilemma. I'm looking at these two karyotypes. Karyotype 1: http://www.biotechnologyonline.gov.au/images/contentpages/karyotype.jpg [Broken] Karyotype 2:http://www.contexo.info/DNA_Basics/images/karyotype1.gif Now karyotype 1, each chromosome is depicted as 2 bars. In karytope 2, each chromosome is depicted as 2 Xs. Which one is it? Is the one bar a more condensed version of one X. It's confusing me because many pictures of mitosis show the replication of a bar, then when duplicated its the sister chromosomes depicted as an X, and then they split again as a bar, like the image here:http://upload.wikimedia.org/wikipedia/commons/e/e0/Major_events_in_mitosis.svg. The way this looks to me, a somatic cell appears haploid because the chromosome looks singular rather than a pair after it's divided. Now if that one bar was actually an X, then it would totally make sense to me. Any help is greatly appreciated. Thanks.
