Which cross will yield four phenotypes in the 1:1:1:1 ratio? rryy x rryy
RrYy x RrYy
RRYY x rryy
RrYy x rryy

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
