Answer 1

If you are running a farm, wherein crops and livestock are your primary source of income, then it is highly important for you to find the best way to boost your efficiency. Take note that natural or organic farming does not always ensure best results, but there is one very good agricultural method for higher production—selective breeding.

Selective breeding is used to hereditarily encourage beneficial characteristics on both animals and plants. Basically, it is performed through controlled breeding. But like any other agricultural method (though they are supposedly designed to offer advantages for society), it also has its own set of disadvantages. If you are thinking of applying selective breeding into your crops and livestock, weigh them down to come up with a decision whether it is a great option for you.

List of Advantages of Selective Breeding

1. It requires no company patent. 
Any person who works in agriculture can start selective breeding whenever he wants. It is a way for him to naturally earn more income each year as he can breed specific characteristics into animals and plants to make them produce more over generations in the future, which is good for business. And since it is free, he just needs to be well-equipped and knowledgeable of the process to get the best outcome.

2. It allows for higher profit. 
Selective breeding allows the encouragement of plant and animal characteristics that are more beneficial to farmers. For example, if they have selectively bred cows, these livestock can produce more milk than those typically bred, and the gene can be passed on to their offspring. When the method is used on crops, they will also grow more than the typical crops. Promoting these advantages is surely going to increase the market value of their products. For farmers who are in for a big business, selective breeding is definitely a perfect option for them.

3. It can create new varieties of good crops. 
With this farming method, people will be able to produce higher amounts of crops. They can also produce plants with higher resistance to pests and diseases, not to mention the shorter period of time for harvest.
