What are the advantages and disadvantages of self-pollination and cross-pollination?
Self pollination does not require pollinating agency and it is accompalished with lesser amount of material (pollen grains) but selfpollination leads to homozygosity and sometimes sterility due to lethal genes. Cross pollination helps in genetic advancement and evolution of hybrids and it is preferred by majority of plants. Although cross pollination reqiures plenty of pollenating material and presence of pollinators.
What are the 2 different methods of pollination?
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
The evolution of flowering plants and insects that transport their male gametes is an example of what?
This is an example of coevolution, where two or more species reciprocally affect each other's evolution. In this case, the flowering plants and insects have evolved traits that benefit each other, such as the plants producing nectar for the insects in exchange for pollination services.
Why cross pollination is better than self pollination?
Advantages: 1. Hybrid vigour is maitained, 2. Chances of aquiring broad genetic base are always there. 3. Process of evolution continues. Dis-advantages: 1. Seed formation always depend on availability of pollinator 2. Lots of variability leades to heterozygocity and inconsistancy in phenotypes. 3. Mixing of inferior genes takes place if pollinators are not controlled.
How is self pollination different to cross pollination and how are they alike?
Self-pollination occurs when pollen from the male part of a flower fertilizes the female part of the same flower or another flower on the same plant, while cross-pollination involves the transfer of pollen from the male part of one flower to the female part of a different flower, typically from a different plant. Both processes result in fertilization and can lead to the production of seeds. They are alike in that both are essential for plant reproduction and can contribute to genetic diversity, although self-pollination generally leads to less genetic variation compared to cross-pollination.
What kind of pollination increases variation within a plant species?
Cross-pollination increases variation within a plant species by introducing new genetic material from multiple individuals. This leads to increased genetic diversity and the potential for beneficial traits to emerge through recombination.

Why cross pollination takes place?
To create more genetic variability so as give momentum to the process of evolution.
What is Different between self pollination and cross pollination?
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
Distinguish between self-pollination cross-pollination?
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
What are the types of pollination?
