The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Because the allele for white fur is recessive, the only possible genotype for a white-fur mouse is ff.Because both parents can only pass down an fallele to the offspring, all of the offspring will have the ffgenotype aswell, resulting in 100% white-fur offspring.
