In pea plants, round peas are dominant (r) and shriveled peas are recessive (r), and yellow peas (shown as light gray in the punnett square) are dominant (y) and green peas (dark gray) are recessive (y). using this information and the partial punnett square shown, what is the phenotypic ratio of the offspring pea plants in this punnett square?

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.
