3. What is the definition for the word MOSAIC in the following sentence.

3. Calicos are essentially a three-dimensional MOSAIC of two cell types, one with genes for black-and-white coat patterns, the other with genes for orange and white. Because CC was cloned from a single cell, she got only the black-and-white gene, unlike her "mom," the typical calico mix of both types.
