Chromosome mosaicism is defined as the presence of two or more cell lines with different chromosome constitutions in a single individual. Chromosome analysis to rule out mosaicism from solid tissue includes routine karyotyping using G-banded preparations. A minimum of 50 cells are counted and 5 cells are analyzed for chromosomal abnormalities.
