Monarch Butterflies Danaus Plexippus Are Best Known For Their Long Distance Annual Migration In North America Interes 1 (41.24 KiB) Viewed 8 times

Monarch butterflies (Danaus plexippus) are best known for their long-distance annual migration in North America. Interestingly, monarchs are also found in smaller populations around the world, including the Pacific Islands and southern Europe. These smaller populations are non-migratory or travel only short distances. Recent genomic analyses suggest that monarchs colonized other locations throughout the world from North American origins. Researchers observed little to no genetic differentiation within the North American Monarch population: however, they see high genetic differentiation between populations of Monarch butterflies that are separated by large bodies of water. Which of the following statements is MOST consistent with the information provided? (credit: Bio240 student) O a As a consequence of founder effects, a population of monarch butterflies found on a Pacific Island would have a higher degree of genetic variation than a population of North American butterflies. Ob The North American monarchs have been continually exposed to a pesticide over many generations. Since butterflies with greater pesticide resistance will be selected for this population can be said to be in Hardy-Weinberg equilibrium Oc Mating between monarchs from North America with monarchs from southern Europe will be unsuccessful since these butterflies have undergone allopatric speciation Od. The lack of genetic differentiation amongst North American monarchs results from high levels of gene flow within this population
