In a cross between homozygous wild-type drosophila and yellow-bodied males of all of the f1's were phenotypically wild-type. the f2 generation (resulting from matings of the f1's) had 356 wild-type offspring. however, all 240 females were wild-type and of the 239 males, 116 were wild-type and 123 were yellow-bodied. how is the yellow-bodied trait inherited?

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.
