Biology Question on Strategies For Enhancement in Food Production
In maize, hybrid vigour is exploited by:
A
bombarding the protoplast with DNA
B
crossing of two inbreed parental lines
C
harvesting seeds from the most productive plants
D
inducing mutations
Answer
crossing of two inbreed parental lines
Explanation
Solution
Hybrid vigor, also known as heterosis, is often achieved by crossing two inbred parental lines to create hybrid offspring that exhibit superior traits and performance compared to either of the parental lines. This phenomenon is commonly used in agriculture to increase crop yields and improve other desirable characteristics in plants like maize.
So, the correct option is (B): crossing of two inbreed parental lines
