In crop improvement programmed haploids are of great importance because they__________________?
Correct answer: C. Give homozygous lines following diplodization
- A. Are useful in studies on meiosis
- B. Grow better under adverse conditions
- C. Give homozygous lines following diplodization
- D. Require only about half the amount of chemical fertilizers compared to diploids
Explanation
Haploids contain one chromosome set, so chromosome doubling produces completely homozygous diploid lines in a single generation. This greatly speeds the production of pure lines in crop improvement.
