Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.

The time required for the colony to grow two million bacteria is 29.22.
Explanation:
Time required for the colony to grow can be calculated by the following equation:
Here t is time, N = 2 million (require bacteria population).
t ≈ 29.22
Time taken by bacteria to grow is 29.22.
