← HistoryWhich outcome resulted as maize was transferred from Mesoamerican chinampas to varied Andean terraces?
A)Decreased overall crop genetic diversity✓
B)Improved nitrogen fixation by companion plants
C)Reduced susceptibility to widespread blight
D)Increased resistance to arid climates
💡 Explanation
Decreased crop genetic diversity occurred because of limited initial founding maize populations used in Andean terrace experiments; therefore, vulnerability to environmental stressors increased, rather than adaptation observed with in-situ chinampa polyculture.
