In drosophila ,vestigial (vg) wings and reduced (rd) bristles are both recessive mutations in drosophila. vg and rd are both found on chromosome 2, which is depicted in the map below. a female from a homozygous strain of vestigial flies was crossed with a male from a homozygous strain of reduced bristle flies. the f1 hybrids were phenotypically wild-type (long wings and normal bristles). if a female f1 fly is mated with a vestigial male having reduced bristles, what proportion of the progeny would have long wings and normal bristles?

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.
