The answer is I, evolutionary phylogeny; It is based on the phylogeny of organisms which is determines the similarities and differences in their physical or genetic characteristics. A phylogenetic tree or evolutionary tree is used which shows the inferred evolutionary relationships among various biological species or other entities.

Answer: D
Explanation:
Crossing over refers to homologous chrosmomes exchanging DNA which creates variation of chromsoomes that are inheried by offspring.
Answer:
B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
Explanation:
In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells.
So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.
