What is the benefit of cross pollination over self-pollination?
Advantages of cross-pollination over self-pollination. (1) It always results in much healthier offspring which are better adapted to changed environment. (2) Promotes genetic diversity in plants. (3) Production of hybrid instead of pure lines.
What are the advantages and disadvantages of cross pollination to the plant?
| Advantage | Disadvantage |
|---|---|
| Heaithier offspring | Pollination is not always sure |
| New varieties can be produced | Lot of pollen is produced & wasted |
| Speeds are abundant and good quality | Flowers may have to be large, showy, scented, have nectar |
What are advantages of self pollination?
The advantages of self-pollination are as follows: Much surer in bisexual flowers where stamens and carpels mature simultaneously. Indefinite preservation of parental characters. No wastage of pollen grains.
Which is not an advantage of cross pollination?
1 Pollination may fail due to distance barrier. 2 Flowers have to totally depend on the external agencies for pollination. 3 More wastage of pollen. 4 It may introduce some undesirable characters.
What are the advantages and disadvantages of self pollinated flowers?
Advantages of self-pollination A very few pollen grain can pollinate the flower. Purity of the race is maintained. Self-pollination avoid wastage of pollen grains. Less chances of failure of pollination.
How does cross pollination produce better and higher quality fruit?
Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees with desired attributes.
What are the five advantages of self-pollination?
The advantages of self-pollination are as follows:
- Much surer in bisexual flowers where stamens and carpels mature simultaneously.
- Indefinite preservation of parental characters.
- No wastage of pollen grains.
- Flowers are not required to be showy and large.
- Nectar and scent are not required to be produced by flowers.
How does cross pollination form a better progeny?
Cross pollination forms a better progeny because it allows for diversity in the species, as the genetic information of different plants are combined. However, it relies on the existence of pollinators that will travel from plant to plant.
What are the characteristics of cross pollination?
Cross-Pollination. In this type of pollination, the pollen is transferred from the anthers of one flower to the stigma of another flower. In this case, the two flowers are genetically different from each other. Cross-pollination is always dependant on another agent to cause the transfer of pollen.
What are the three advantages of self-pollination?
Which of the following agent is most useful in cross pollination?
Insects are the most common of them. Beetles, Bees, Moths, and birds are examples of biotic pollinating agents.
What are the advantages of the following in the flower to the plant concerned?
a) The long and feathery stigma are advantageous to plants to catch the pollen. b) The brightly coloured petals are for attractung the various agents for pollens. c) If the pollen is smooth and light,It can easily dispere away with the air and can pollinate the stigma.
