"White-furred rats may outnumber black-furred rats due to natural selection, genetic drift, and potential mating preferences favoring white fur."
"Rats with white fur might outnumber black-furred rats due to natural selection, as white-furred rats may be better adapted to their environment. Genetic drift could also play a role, resulting in a higher number of offspring for white-furred rats by chance. Additionally, there could be a mating preference in the population favoring white fur. These factors combined could lead to the increased prevalence of white-furred rats."
Shorten this down a LOT.
