A
A method used in industrialized agriculture to favour genetic uniformity, resulting in high crop yields under specific regimens of irrigation and fertilization.
2
Q
What is genetic erosion?
A
A process by which a limited gene pool diminishes further.
3
Q
What is the estimated annual rate of genetic erosion in crop varieties?
A
1-2%.
4
Q
What is the impact of a loss of agricultural biodiversity?
A
It makes crop plants genetically vulnerable, threatening them with extinction due to a lack of genetic diversity.
5
Q
What could happen without genetic variation in crops?
A
A new strain of disease could adversely affect all members of the species.
