So we keep all other variables the same. The variables we keep the same are called... Type of reproduction that leads to variation of traits The process of changing one form of energy to another form of energy. The variable that we measure in an experiment (the effect) The variable that we make different in an experiment (the cause) A chart that shows all the possible combinations of alleles that can result from a genetic cross of 2 parents Type of reproduction that leads to NO variation of traits Organisms with the better genes survive and those alleles get passed on the offspring The transfer of energy from one object to another object Causes of genetic variation
