History

Which 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.
