There are three types of dominance. Incomplete, complete, and co-dominance. Complete dominance is when the dominant trait completely masks the recessive. incomplete dominance is when the dominant allele doesn’t completely mask the recessive allele, sometimes resulting in blending. Co-dominance occurs when both alleles are expressed at the same time.
I would say no because not all DNA is the same so some may respond differently
The process that occurs in the mitochondria is cellular respiration. It is on the cristae that cellular respiration occurs, where food is converted into another usable form of energy. Most of the energy producing reaction which occur in the mitochondria, happens in the surface of the cristae.
