Implications doesn't mean BAD things. It just means advantages/disadvantages. The implications of self pollination are:
- No pollinating agent is required
- Less variation as there is no exchange of genetic material from different plants
- Is much faster then cross pollination
- Much higher chance of pollination
- Plants are unable to colonize new areas as the pollen grains are not transferred from one plant to the next.
Advantages of cross pollination are:
- Results in variation
- Plants are able to colonize new areas as pollen grains are spread by pollinating agents.
Thanks alot, but one thing.. colonise in new areas, isnt that for the advantages of seed dispersal?
