What is a photograph of individual chromosomes called?

I think there is a spelling mistake here, its karyotype.

The correct answer should be "karyotype". Using karyotype, we can photograph a complete set of chromosomes from a cell during cell division, most efficient during metaphase.

The answer should be karyotype right ? Not Karotype. Or it can be written in either Karotype/Karyotype ?

Karyotype isthe number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
