Question

Advantage and disadvantage of selective breeding in fish

Answer 1

List of Advantages of Selective Breeding

1. It can result to more produce and agricultural products.
One of the advantages of selective breeding is the possibility of gaining higher profit with the process. An example is when cows that have the characteristics to produce more milk other traditionally bred cows are selectively bred. These cows will produce offspring that will also have the same traits. Same goes with plants that undergo the process. If plants or varieties bear abundant fruits or crops, they can be breed selectively to produce more crops that can be sold for higher profit.

Disadvantages of Selective Breeding

1. There is the possibility of genetic mutation.
One disadvantage that is seen by experts is the lack of control in preventing the offspring from having unfavorable traits. An example is when genetic mutation occurs in planted crops. The sad part is, most of these mutations do not offer benefits. In this method or process, the formation of genes cannot be controlled or regulated.

2. This can result to the lost of genes from the genetic pool.
Since animals and plants will be chosen for their certain characteristics and bred with other species that also have specific traits, the offspring might be entirely different. Consequently, there is the risk to lose some of the genes coming from the parents and in the end, it will be difficult to bring it back to the next generation.

3. This can result to risks of having diseases.
Selectively bred animals and plants can lead to offspring having similar genes and at the same time, it will result to diseases becoming more dangerous. Aside from this, there is also an increased possibility of having genetic diseases like cystic fibrosis caused by recessive alleles.

Answer 2

Advantage:It can result more produce and agricultural product

Disadvantages:There is the possibility of genetic mutation
