Question

Which cells cannot be used to produce a karyotype?
A) white blood cells
B) red blood cells

Accepted Answer

Red blood cells (erythrocytes) do not have a nucleus and therefore cannot be used to produce a karyotype, which requires imaging and analysis of the chromosomes within the nucleus of a cell.
