Question
When two unrelated individuals or lines are crossed, the performance of F1 hybrid is oftensuperior to both its parents. This phenomenon is called
Options
A.transformation
B.splicing
C.metamorphosis
D.heterosis
Solution
(a) [Key Concept: Heterosis — Hybrid Vigour] HETEROSIS (or hybrid vigour) is the phenomenon where F1 hybrids between two unrelated individuals or inbred lines are superior to both parents in traits like growth, vigour, yield, and fertility. This is widely exploited in agriculture (hybrid maize, rice, etc.). The genetic basis includes overdominance, dominance, and epistasis. Transformation is uptake of foreign DNA by bacteria; splicing refers to RNA processing; metamorphosis is developmental change in form.
