Hybrid vigour is best maintained in vegetatively reproducing plants because they area)Resistant to diseasesb)Easily propagatedc)With long life spand)Little liable to lose vigour due to absence of sexual reproductionCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Vegetative reproduction occurs by mitosis division so there is no chance of crossing over so the character posses by hybrid vigour do not loss but in sexual reproduction meiosis occur.

Answer

Vegetative reproduction occurs by mitosis division so there is no chance of crossing over so the character posses by hybrid vigour do not loss but in sexual reproduction meiosis occur....

Answer

Option D is correct answer bcoz the plants produced via vegetative propagation are little viable to lose that vigour as they lack sexual reproduction which actually brings variations and recombinations....

Answer

The Hybrid Vigour is best maintained in vegetative reproducing plants as because they are little liable to loss vigour due to absence of the sexual reproduction. In case of the vegetative reproduction, a new plant body can be developed from a part of old plant body

Answer

Hybrid vigour is best maintained in vegetatively reproducing plants because they are:

a) Resistant to diseases:
Vegetatively reproducing plants, also known as clones, are genetically identical to the parent plant. This means that if the parent plant is resistant to diseases, the clones will also inherit this resistance. By maintaining the genetic makeup of the parent plant, vegetative reproduction helps to maintain the resistance to diseases in the offspring.

b) Easily propagated:
Vegetative reproduction involves the production of new plants from vegetative parts such as stems, leaves, or roots. This method of reproduction is relatively easy and does not require the formation of flowers or seeds. It allows for the rapid and efficient production of offspring, resulting in a large number of plants with hybrid vigour.

c) With long life span:
Vegetatively reproducing plants tend to have longer life spans compared to sexually reproducing plants. This is because vegetative reproduction allows for the perpetuation of the same genetic material without the need for sexual reproduction, which can be energetically costly and may lead to genetic recombination. The longer life span of vegetatively reproducing plants helps to maintain hybrid vigour over extended periods.

d) Little liable to lose vigour due to absence of sexual reproduction:
Sexual reproduction involves the fusion of gametes from two different individuals, resulting in genetic recombination and the creation of offspring with a new combination of genes. While sexual reproduction can increase genetic diversity, it can also lead to the loss of favourable traits or the dilution of hybrid vigour. In vegetatively reproducing plants, the absence of sexual reproduction means that there is no genetic recombination, and the offspring maintain the same genetic makeup as the parent plant. This helps to prevent the loss of hybrid vigour and ensures that the desirable traits of the parent plant are preserved in the clones.

In summary, vegetative reproduction is advantageous for maintaining hybrid vigour in plants because it allows for the preservation of disease resistance, easy propagation, longer life spans, and the absence of genetic recombination that may lead to the loss of vigour.
