What is a dichotomous key? How could you go about constructing your own dichotomous key for a random collection of organisms in the wild?
A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA.
Based on this information, which order should they go on the cladogram (from least related to most related)?
Imagine you are studying two eukaryotic species. The genome of Species A is 100
Mb in size. The genome of Species B is 500 Mb in size. Based only on this
information, which of the following statements are accurate?
Species B is a more complex organism than Species A.
None of the other statements can be made based solely on the information in
the question.
Species B has more genes than Species A.
Species B has more chromosomes, more genes, and is more complex than
Species A.
Species B has more chromosomes than Species A.
