Crop Genetic Diversity

APBIO-RFWN2Q

Maize (corn) was domesticated about 10,000 years ago. Genetic evidence suggests that maize developed from a wild plant called teosinte. Early farmers in what is now Mexico artificially selected maize to increase traits, such as number of ears produced, number of kernels, and size of kernels.

How does the genetic diversity of a modern corn field compare to the genetic diversity of a population of teosinte?

A

Less diversity.

B

More diversity.

C

More genetic diversity, but less phenotypic variation.

D

The same amount of diversity.
