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.
End product of replication is the same to which you have replicate.....but they get increased in quantity.......
The noble gases already have a full outer shell. The noble gases break the trend by being less reactive than the elements to their left.
