Question

27 an analysis of dna and rna sequences can be used to classify organisms. a dendrogram, such as the one shown below, is based on molecular data. it can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. which statement is best supported by the information in this dendrogram? a lesser pandas are more genetically similar to giant pandas than they are to raccoons. b brown bears are more genetically similar to giant pandas than they are to sun bears. c lesser pandas are more genetically similar to raccoons than they are to giant pandas. d the bear species are all more genetically similar to dogs than they are to giant pandas. 42 genome maps provide the dna sequences of chromosomes. some scientists have compared the genome maps of a hedgehog and a sloth. what do these genome maps allow the scientists to determine? f the color patterns of the offspring of each species g how much the size ranges of the two species differ h the methods of protein synthesis that each species uses j how closely related the two species are to each other

Explanation:

For the first question, in a dendrogram, organisms that branch off closer together are more genetically similar. Lesser pandas and raccoons branch off from a common point closer in time compared to lesser - pandas and giant pandas, indicating greater genetic similarity. For the second question, genome maps show DNA sequences, and comparing them allows scientists to determine the genetic relatedness between species.

Answer:

1. C. Lesser pandas are more genetically similar to raccoons than they are to giant pandas.
2. J. How closely related the two species are to each other
