The best statement that explains why the nucleotide diversity of red pandas decreased over five generations is:
"As the population of red pandas decreased, there was a lesser number of genes to be passed down."
This response aligns with the concept of genetic drift and reduced genetic diversity that occurs in smaller populations. As the population size decreases, the potential for varied genes being passed down also decreases, leading to lower nucleotide diversity.
