Because the majority of crops (cereal crops) are wind pollinated.
Why hybrids are not successful in self pollinated crops?
In self pollinated crops, hybrid vigour is not just like the cross pollinated crop e.g maize.cross pollination in self pollinated crop produce low seed set and cost of hybrid seed increases.less cytoplasmic male sterility and fertility restorer gene in mostly self pollinated crop.
What is special about the bee?
About 70% of food has to be pollinated by bees - not bees, no fruit or vegetables.
What effect does pollen from genetically modified plants have on organically grown plants when they are cross pollinated?
When organic crops are pollinated with GMO crops, the GMO gene can become a part of the organic crop, so the organic seed for the following year contains the GMO. Technically, since organic crops are not supposed to have GMOs in them, this contaminates the organic crops.
How long will the human species survive?
If all animals died then they could survive for a few months. They might be able to eat vegetables for a while but most fruit and cereal crops are pollinated by bees so these would also die out.
Do bees polinate vegtables?
Yes, bees pollinate vegetables as well as decorative flowers. Examples of bee pollinated vegetables are peas and beans.
What happens when most cross-pollinated crops are self-pollinated for several generations?
you'd get a uniform genetic composition for good or bad. you can get a uniform crop or you may get inbreeding problems
Can you eat crops?

What percentage of food crops are pollinated by insects birds or mammals?
approximately 3/4 or 75%
What is the definition for mixedcrops?
