Question

what are the advantages and limitations of sexual reproduction​

Answer 1

Explanation:

The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population.

Advantages of sexual propagation :

-Seedling trees are generally long-lived, bear more heavily and arecomparatively more hardy.

-This is the only means of reproduction, where asexual propagation is notpossible or economical, e.g., papaya, phalsa, mangosteen etc.

-To develop new varieties, hybrids are first raised from seeds and it isessential to employ this method in such cases.

- It has been responsible for the production of chance seedlings of superiorattributes.

-Polyembryonic character exists in many fruit plants such as in some citrusspecies and some mango varieties and give rise to more than one seedlingfrom one seed. The nucellar seedlings are true-to-type. Therefore,polyembryomic varieties can be propagated by seeds.

-Rootstocks upon which the fruit varieties are budded or grafted are mostlyraised from seeds.

-Seedlings are cheaper and easy to raise.

-Seeds can be easily transported to distant places.

- Does not require high technical knowledge and skilled labour.

Limitations of sexual propagation :

-Seedling trees are not uniform in their growth, yielding capacity and fruitquality.

-Seedling trees have long juvenile period and take more years to bear thefirst crop.

-Seedlings become large for economic management.

- It is not possible to maintain the exact character of any superior selection.

- Seed propagation can't be applied in many plants e.g. banana.
