Question

‘Teosinte’ is considered as ancestor of:

A.

Maize

B.

Mustard

C.

Rice

D.

Wheat

Correct option is A

The correct answer is: (A) Maize
Explanation:
Teosinte is a wild grass native to Mexico and Central America, and it is considered the ancestor of modern maize (Zea mays). Through thousands of years of domestication and selective breeding,
early agricultural societies transformed teosinte’s small, hard kernels into the large, soft, and edible kernels of modern maize (corn). Genetic studies have confirmed the evolutionary link between teosinte and maize.
Information Key Points:
  • Morphologically different but genetically very similar to maize.

  • Domestication began over 9,000 years ago in Mexico.

  • Maize developed from teosinte by human selection for favorable traits.

Knowledge Booster:
  • Mustard: Has different wild ancestors within the Brassica genus.

  • Rice: Descended from wild species such as Oryza rufipogon.

  • Wheat: Evolved from wild species like Triticum urartu and Aegilops speltoides.
