Pros and Cons of Selection Practice Test

A tomato grower practices selective breeding by saving seeds only from plants that produce the sweetest tomatoes (measured by sugar level). After 3 generations, average sugar level rose from 4.8 to 6.1 (Brix). But the number of tomatoes per plant dropped from 30 to 22. Which statement is best supported by the evidence and balances benefits and concerns?

A lab uses genetic selection on a population of fruit flies: only flies that survive exposure to a pesticide are allowed to reproduce. After 10 generations, survival during pesticide exposure increased from 15% to 80%. But in pesticide-free conditions, the selected flies produce fewer offspring per female (average 40) than an unselected population (average 65). Which statement best balances benefits and concerns using the evidence?
