When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it. This causes the refrigerant to absorb heat from the warm air and reach its low boiling point rapidly.
lets first label the genotypes
ex: pure bred red plant = ff
white flower plant = ff
so if you cross breed the two flowers, the genotype would be most likely i think hehehe
