Answer:
A mutation in the DNA sequence of the gene for brown fur
Explanation:
The mutations are capable of changing the encoded protein product, in this case the gene that encodes for the fur color pigment. This mutation may have occurred during mitosis or meiosis divisions.
If it is a spontaneous mutation that occurred in the germinal line (meiosis) and confers an adaptive advantage, it will increase their frequency in the population.

Important factor defining the desert biomes is its tendency to lose water by evaporation, and this potential for water loss exceeds the annual rainfall and defines what organism can live in there.
In multicellular organisms, the shape of the cell helps determine its function. For example, red blood cells are donut-shaped to easily exchange oxygen and freely pass through narrow blood vessels while nerve cells are long so when connected to other nerve cells they can span long distances in the organism
