The scatter profile of a chromosome karyotype on a microscopic slide. Well spread chromosomes enable the karyologist to count and pair the chromosomes, and classify the organism to species level.

Jane: Thanks, I dropped the cells from two feet up!
Bob: As they say, "Happiness is a good spread," I hope you get good G-banded karyotypes.
