Answer 2

D. A mouse and a human have about the same number of genes.

Explanation - The number of chromosomes does not determine the complexity of the organism. A mouse and a human have approximately same number of genes. Mice is biologically the same as people since they perform comparable capacities and procure comparative diseases as people.

That is why several experiments are conducted in mouse to understand how the reaction will take place in humans. After all the trials are passed, then the experiment is conducted on humans.
