Question

What are the advantages of Self pollination and cross pollination??​

Answer 1

${\mathfrak{\blue{\underline{\underline{Answer:-}}}}}$

Advantages of Self pollination:-

✪ Less chance of failure of pollination.

✪ It helps in maintaining purity of race.

✪ Large numbers of organism are produced.

✪ Self pollination are generally faster.

✪ Traits are genetically identical so advantageous traits are not lost.

Advantages of Cross pollination:-

✪ It gives multitude of features.

✪ The genes have a larger chance of survival if a disease hits.

✪ Breed new variety of species.

✪ Scope of evolution.

✪ Seeds are more viable and healthier with better germinating capacity.

❇ Self pollination :- Self pollination is the transfer of pollen from the stamen to the stigma of the same flower or the flowers on the same plant.

❇ Cross pollination :- Cross pollination is the transfer of pollen from the stamen of one flower to the stigma of another flower on a different plant of a same kind.

Answer 2

Explanation:

${\huge{\bold{\orange{\underline{Answer:}}}}}$

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

Advantages of cross-pollination:-

• Cross-pollination is beneficial to the race of the plant as it introduces new genes into the lineage as a result of the fertilization between genetically different gametes

• Cross-pollination improves the resistance of the offsprings to diseases and changes in the environment.

• The seeds produced as a result of cross-pollination are good in vigor and vitality.

If there are any recessive characters in the lineage, they are eliminated as a result of genetic recombination.

• It is the only way unisexual plants can reproduce
