Anew species of grass has been identified with two genes located 10 cm apart. gene a produces a hormone that causes stems to grow. gene b produces small seeds. both genes show complete dominance over their recessive forms. a pure-breeding plant with a long stem and large seeds is crossed with a pure-breeding plant with a short stem and small seeds. the f1 offspring are then crossed with each other to produce the f2 generation. what are the expected phenotypic ratios of the f2 generation?

C. F1 generation is all Yy (let Y be yellow and y be green). Y is dominant to y. The F2 could be YY, Yy, Yy, or yy. 3:1

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.
