In the pedigree below, three mtdna variants are present in generation i, each variant represented by a different color. the dashed lines indicate a mating to an individual in the same generation on the opposite side of the pedigree. for the individuals in generations ii through v, indicate which mtdna variant they inherited by dragging one of the pink, blue, or orange labels to each target in the pedigree. then complete the statements below the pedigree by dragging one white label (with the number 1, 2, or 3) to each statement. labels may be used once, more than once, or not at all.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
