You generated a plant that is heterozygous for two quantitative trait loci (qtl). in the heterozygous state, each locus has one allele that contributes one dose of trait (pigment) and another allele that does not contribute a dose to the trait; genotype: r1/r1; r2/r2. if you testcross this plant (by r1/r1; r2/r2 all ò0-doseó alleles) what distribution of pigment doses would be observed in the progeny?

Identify any four organelles that should be present in the eukaryotic organism and describe the function of each organelle

Which law represents a balanced chemical equation?

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.
