give two advantages & disadvantages of self polination & cross polination....
Answers
Explanation:
2. traits are genetically identical so advantageous traits are not lost. 3. Self pollination are generally faster.
...
Causes variation in gene pool thus giving more survival advantage to the species.
Seed sare more viable and healthier with better germinating capacity.
Scope for Evolution.
Breed new variety of species.
Answer:
- Advantages of self pollination are
1.large number of individuals are produced and
2.traits are genetically identical so advantageous traits are not lost.
3.Self pollination are generally faster.
4.Less chance of failure of pollination.
- Disadvantages of self pollination
1. No variations occurs if plant gets hit by a disease there is no possibility of survival and population decreases.
2.It does not result in creation of new species.
3. Continuous self pollination results in weak progenies
- Advantages of Cross Pollination
1. Causes variation in gene pool thus giving more survival advantage to the species.
2.Seedsare more viable and healthier with better germinating capacity.
3.Scope for Evolution
4.Breed new variety of species
- Disadvantages of Cross pollination
1. Consumes more time and effort.
2.Natural process of pollination becomes delayed in this case.
