The basic method is quite simple. If you breed from the hen which lays the most eggs, the chances are that her daughters will also be good layers. This is because the number of eggs which a hen lays is partly controlled by the genes which a hen inherits from her parents.
Simply so, how is selective breeding done in chickens?
How is it done? The principle of selective breeding is simple – it relies on the selection of individual animals which show the most desirable characteristics as the parents for the next generation in the breeding program, and repeating this process over many generations.
In this way, how much does selective breeding cost?
Financial Requirements and Costs of Selective Breeding
However, in general controlled breeding is a low-cost technology. If stones are locally available and can be used to build the mating pens, an average investment would come to around US$ 30.
Is it proper to continue selective breeding?
Selective breeding can develop desirable traits in plants and animals, but there can be negative effects as well. Without selective breeding, many domestic animals would not exist and many plants that we rely on for food would not be as productive as they are.
What are examples of selective breeding?

- chickens that produce large eggs.
- wheat plants that produce lots of grain.

What is one advantage to selective breeding with chickens?
Chickens could be selectively bred so that hens lay eggs earlier in their development and for a longer period over their life. 8. The cost of selective breeding is minimal. Compared to GMO research or other forms of food chain improvement, selective breeding has a cost that is very minimal.

Selective breeding was established as a scientific practice by Robert Bakewell during the British Agricultural Revolution in the 18th century. Arguably, his most important breeding program was with sheep.
Why do farmers use selective breeding?
Farmers selectively breed different types of cows with highly desirable characteristics in order to produce the best meat and dairy. This means the farmers can make the most profit. Characteristics can be chosen for usefulness or appearance. The new varieties may be economically important.
Why is selective breeding bad for chickens?
