Mendel selected seven traits to analyze in his famous pea plant crosses, and all of these traits yielded expected 3:1 phenotypic F2 ratios in monohybrid crosses. He was fortunate in his selection of these traits
How so? What problem might he have encountered that may have yielded confusing ratios?
By chance, some of the traits he selected might not have been independently assorting, owing to linkage (presence on the same chromosome).

Answer the following statement true (T) or false (F)
Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. Slugs prefer to eat pink-flowering over white-flowering plants (due to chemical differences between the two), and plants experiencing severe
herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so that Claytonia with pink flowers have greater relative fruit set than Claytonia with white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. Given no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time? A) The percentage of pink flowers should increase over time. B) The percentage of white flowers should increase over time. C) The distribution of flower colors should not change. D) The distribution of flower colors should randomly fluctuate over time.
