Benefits and Risks!
in plants These methods of selective breeding can potentially positively influence world food production in these ways
improved quality of seed grains, increased levels of proteins in forage crops. It is also beneficial by helping the plants
to be more resilient to insects and disease. They are also making them to have a capacity to grow on lands that are
not suitable for them to grow in which can be a benefit and that way you can get more food and a variety of different
plants even if it is in a land which can’t suit them.
In animals the mothods of selective breeding can produce fitter and stronger animals that are of a higher yield of milk,
meat or eggs for example some cows are been breed to produce more meat . This can be good as we can produce animals
better suited to survive in poor climates or marginal conditions and this can preserve human food supplies and can save life.
Also for some animal’s selective breeding can protects them from developing diseases like the breeding of sheep’s without
tail and that can help them not to get affected by a disease.
Selective breeding is also a risk of changing the evolution of the species and because humans are breeding different species for
a particular trait this can lead for a risk of losing some of the other genes from the gene pool altogether which is very hard to
For example for plants selective breeding could cause environmental problems if the plant which is selectively reproduced and it
uses more water than other plants around it causing the plants around it to dry out and birds to lose homes and insects to lose food.
The process alters which traits are exhibited in subsequent generations by allowing only the plants with a desired trait to
breed can make the other plants in the place die out.
