Energy due to motion of molecules within a mas is Kinetic
The correct genotypes of the parents are Ttbb male and the TTBb female and the <span>TtBb for the offspring.
The image below presents a cross of these two genotypes </span>Ttbb and TTBb.
As you can see marked with green, 1/4 of the offspring would have the TtBb and be heterozygous for both traits.
The rate of reaction in chemistry tells us how fast a reaction will occur from start to end.
Liver would be the answer. Hope this helps. :)
