Which risk increased in early Mesoamerican maize agriculture via genetic selection for larger kernels on the central cob?

💡 Explanation

When maize was initially selected for larger kernels packed densely on the cob, physical constraints led to reduced air circulation and space for individual kernels to develop properly, increasing their difficulty germinating. Therefore, reduced germination occurred, rather than other problems needing toxin exposure, wind stress or specific diseases.

• Which consequence resulted from thermal expansion within the gear train of early marine chronometers during transoceanic voyages?
• Which optical phenomenon causes distorted star positions viewed through Earth's atmosphere, impeding ancient astronomical observations?
• Which primary effect resulted from the use of torsion-powered siege engines during Roman era?
• Which outcome arises when maize cultivation exhausts soil nutrients in ancient terraced fields?
