A. Minor gene and general resistance
B. Polygenic resistance
C. Quantitative resistance
D. All of the above
Answer: Option D
Solution(By Examveda Team)
Horizontal resistance is also referred to as Minor gene and general resistance, Polygenic resistance, and Quantitative resistance.Genetic resistance that is effective at preventing successful attack only by certain races of a pathogen is called specific resistance, whereas resistance that is effective at preventing successful attack by all races of a pathogen is called general (or horizontal) resistance.
Polygenic resistance acts retarding the rate of development of the epidemic rather than delaying its onset.
Quantitative resistance can refer to an incomplete or partial level of resistance phenotype.
