Write note on Ecads and ecotypes.
Answers
Ecotypes are the ecological races in which the variations associated with certain factors of the environment are genetically fixed. A widely distributed species encounters a variety of environmental conditions and a series of variations, often observable morphological variations, develop in course of the species evolution and adjustment. These variations associated with ecological conditions become genetically fixed and such variants are called ecotypes.
Ecads (also called as ecophenes) the plants of same species which differ in appearance such as size, prostrate or erect nature, reproductive vigour etc. in differing environmental conditions. These variations are not genetically fixed, and when transplanted to neutral conditions the variation disappears.
Ecads and Ecotype
Explanation:
Ecads
- Ecads (additionally called as ecophenes) the plants of same species which contrast in appearance, for example, size, prostrate or erect nature, conceptive force and so on in varying ecological conditions
- These varieties are not hereditarily fixed, and when transplanted to impartial conditions the variety disappears
Ecotype
- An ecotype is a variation where the phenotypic contrasts are excessively not many or too unpretentious to even think about warranting being named a subspecies
- These can occur in the equivalent geographic area where distinct habitats surroundings, for example, glade, woodland, marsh, and sand hills give biological specialties.In this way, ecotypes have no ordered position
