How can an offspring with the genotype (RR) have the same phenotype as the offspring with the genotype (Rr)? (R = round seeds AND r = wrinkled seeds)

R is the dominant allele therefore when there is RR the dominant allele will show in the offspring. Likewise, even in Rr the dominant allele is R and therefore it will be shown in the offspring.

Hope this helped!

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
