What is cross pollination advantages and disadvantages?

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 the three advantages of cross pollination?

Advantages of cross pollination:

  • Progeny shows enhanced vigor.
  • Offsprings are more viable and resistant.
  • There is a possibility to get new desirable characters.
  • Yield of crop can be maintained.
  • It helps in evolution.
  • Undesirable characters of the plant can be eliminated.

What is cross pollination answer?

Cross-pollination, also called heterogamy, type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.

Which is cross pollination?

Cross-pollination is the process of applying pollen from one flower to the pistils of another flower. Pollination occurs in nature with the help of insects and wind. This process can also be done by hand to produce offspring with desired traits, such as colour or pest resistance.

Why is cross pollination bad?

Sometimes it’s actually a bad idea to cross-pollinate because the harvest would increase too much. Fruits would stay small and branches may break off. Additionally, trees that bear too many fruits will age and perish within a few years. Over-pollination exhausts the mother plant.

What is the disadvantages of cross pollination?

It is not always certain as a pollinating agent is always required, and it may or may not be available at the suitable time. Pollen grains have to be produced in abundance to ensure chances of pollination. This results in lot of wastage of pollen.

What is the result of cross pollination?

Cross pollination is when one plant pollinates a plant of another variety. The two plants’ genetic material combines and the resulting seeds from that pollination will have characteristics of both varieties and is a new variety. Sometimes cross pollinating is used intentionally in the garden to create new varieties.

Which is not an advantage of cross pollination?

(2) Cross-pollination is not beneficial from economic point of view. The plants waste a lot of energy on various contrivances required to ensure cross-pollination and there is huge waste of pollen grains in this process.

What is the advantages 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.

How is pollination carried?

Pollen grains are sprinkled on water surface and they are passively transported to the female flower for pollination. In seagrasses, the female flower remains submerged in water and pollen grains are released below the water surface.

What is the likely pollinator for a night blooming white flower with a strong scent?

After dark, moths and bats take over the night shift for pollination. Nocturnal flowers with pale or white flowers heavy with fragrance and copious dilute nectar, attract these pollinating insects. Not all moth pollinators are nocturnal; some moths are also active by day.

What traits might a night blooming flower have to attract nighttime feeders?

Flowers attracting nighttime pollinators might have a strong scent or the flowers might be light-colored so they can be seen in the dark.

Why do white Colour flowers bloom at night?

Night blooming flowers are generally white because at night they do not have to waste resources to secrete out coloured pigments to be visible to insects and at night white colour refracts light which make them visible for pollination.
