Homozygous mutant flies (with the same phenotype as the original stock) would appear in the F1 generation, mixed in with the double heterozygotes (which will have wild type phenotype). More pigment is released from the beetroot cells as the temperature is increased and the phospholipid bilayer becomes progressively more disaggregated because an increase in kinetic energy increases the movement of the phospholipid molecules that make up the membrane.
