← HistoryIncreased susceptibility to fungal disease occurred after early maize domestication because which mechanism dominated?
A)Reduced kernel mechanical defense✓
B)Increased kernel nutritional diversity
C)Enhanced genetic resistance capacity
D)Wider dispersal kernel protection
💡 Explanation
Early maize domestication selected for larger, softer kernels, thereby relying less on mechanical defense; this increased vulnerability to fungal disease because the Kernel Defense Deficiency became prevalent. Therefore, softer kernels become more commonplace rather than preserving existing kernel defenses.
