Chromosomes are arranged based on two main criteria: Total Length (size) and the position of the Centromere (the "pinched" center).
If a worksheet provides a scrambled photomicrograph, the correct Denver System arrangement should be presented as: denver system worksheet karyotype answers
The sex chromosomes (X and Y) are not part of a numbered pair. The X chromosome is included in Group C (size similar to #7), and the Y chromosome is in Group G (similar to #21–22 but without satellites). Chromosomes are arranged based on two main criteria:
A typical karyotype worksheet provides an image of stained, paired chromosomes (or a photomicrograph of a metaphase spread). Students are asked to arrange them according to the Denver System and answer diagnostic questions. denver system worksheet karyotype answers
