Question 15 of 402.5/ 2.5 PointsWhy do so many geneticists focus on studying yeast, fruit flies, nematodes, mice or the smallplant Arabidopsis?A. These pest organisms result in millions of dollars of damage and hurt the economy.B. They are ideal for modeling human disease since they have all the same organs.C. They have multiple features that allow for cheap, fast and efficient manipulation ofgenes and chromosomes.D. They are some of the few organisms in which mutations can be generated.
Feedback:Genetic model organisms have a quick lifecycle, small size, and resilience that makesthem easy to culture in the lab.Question 16 of 40
2.5/ 2.5 PointsFor her science fair project, your little sister replicated one of Mendel’s experiments. From a P0pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (shehad forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7were purple and 1 was white, for a 7:1 ratio.Did your little sister just disprove Mendel’s laws?
Feedback:Learning Objective: Analyze Mendelian and Non-Mendelian inheritance patternsQuestion 17 of 402.5/ 2.5 PointsWhy do bacteria not need telomerase?
