The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: - Answer-the number of occurrences of the allele divided by twice the number of individuals in the sample (2n) If a population is not in Hardy-Weinberg equilibrium, we can conclude that: - Answer-evolution has occurred because one of the assumptions of the Hardy-Weinberg equilibrium has been violated The goldenrod ...

Cladograms Gizmo Questions and Answers Graded A According to the cladogram shown, which organism is most closely related to Arabidopsis? A. Algae B. Moss C. Cycad D. Cannot be determined. C. Cycad In the cladogram shown, Arabidopsis and cycad are directly connected to one another by a common ancestor, so cycad is more closely related to Arabidopsis than moss or algae. Arabidopsis and cycads share the characteristics of multicellularity and xylem and phloem According to the cladogram shown, whi...
