So we keep all other variables the same. The variables we keep the same are called... The variable that we measure in an experiment (the effect) Type of reproduction that leads to variation of traits Organisms with the better genes survive and those alleles get passed on the offspring The variable that we make different in an experiment (the cause) A change in a gene/allele base pair that causes a new allele to be formed that can be passed to the offspring A chart that shows all the possible combinations of alleles that can result from a genetic cross of 2 parents The process of changing one form of energy to another form of energy. Causes of genetic variation
