You need to know if the parents trait are dominant or recessive
Through reproduction. dark fur is a dominant trait and eventually if offspring of the one dark furred mouse reproduce enough, it will eventually spread to the whole population because it is a dominant gene and will overpower recessive genes of the other parent organism that the dominant mouse is reproducing with.
No they don’t, but to be able to have cellular respiration it can perform aerobic cellular respiration. These cells will move electrons back and forth across their cell membrane. Other types of prokaryotes cannot use oxygen to perform cellular respiration, so they perform anaerobic respiration.
