What Are the Benefits of Selective Breeding?

Selective breeding, also known as artificial selection, develops new organisms with desirable characteristics. This form of biotechnology predates Charles Darwin for thousands of years and is responsible for many of the plants and animals we know today. Read on to learn more about this practice and the principles behind it. 

Lesson Pack on Selective Breeding

The lessons in this pack are designed to teach students about the advantages and disadvantages of selective breeding. These lessons include a short article on hybrids and a study on how genetic material is passed from parents to offspring. Students will be given three pages of handouts to complete and answer questions based on the articles. They will also learn about Mendelian genetics and the differences between asexual and sexual reproduction. For older students, you can go deeper into this topic by providing differentiated worksheets for each student.

The resource includes text and videos related to selective breeding. It is designed to teach Tier I science instruction under the RtI model and meets TEKS 7(11) (C) in biology. In addition, students will learn how to recognize the changes in genetic traits over several generations. Before using the resource, review the prerequisites and differentiate for different student populations. It can be delivered in a traditional classroom or using a single computer.

Principles of selective breeding

In GCSE biology, a study of inheritance and the role of selective breeding is often included. Studying the principles of inbreeding and heterosis will introduce the students to these topics. In addition, the principles of selective breeding will be presented, including the principles of mating systems, as well as a brief review of the different types of selection available. Students will also gain insight into the management of breeding programs

The Principles of Selected Breeding was first proposed by Charles Darwin, who repeated references to these principles in defense of his theory of common descent. Darwin pointed out that genetic diversity principles backed up the possibility of evolution and species diversification. Darwin believed that we could extend these principles to dramatic changes in the population over long periods. The observations of plasticity in species have been used to support the theory of evolution.

Cost of selective breeding

Selective breeding involves the selection of animals and plants based on one characteristic. This process produces similar populations with less genetic diversity, making them vulnerable to environmental influences and illnesses. There are enough individuals with different features to avoid these problems in ordinary people. Selective breeding is an environmentally-destructive process that can wipe out entire populations. It can also lead to the development of genetic depression in the offspring. While it is possible to create more desirable traits through selective breeding, it also comes with a price.

During the process of breeding, a breeder can improve several traits. This improves its adaptive power and improves its performance in a variety of environments. For example, heat tolerance is essential for animal reproduction. Other characteristics that may improve with selective breeding include ag-efficiency and resistance to disease. Aside from these benefits, selective breeding is also controversial and can lead to puppy mills. Furthermore, it can also create issues with popular sires and breeds.

Health implications of selective breeding

Selective breeding is a practice that uses artificial selection to direct the genetic transfer of desirable traits to plants and animals. This practice mainly aims to produce animals and plants with desirable characteristics, which in turn benefit humans. Selective breeding involves identifying desirable traits in one or more species members, then finding the two individuals with those traits, mating them, and producing offspring with those features. Finally, the favored phenotypes are passed down through the genes from the parents.

The health implications of selective breeding are many and varied. Although selective breeding can improve the characteristics of many animals, it can also result in weaker individuals that lack desirable traits. For example, some breeds of dogs have soft spines, shortened lifespans, or other undesirable characteristics. In many cases, selective breeding is not beneficial to human health. Ultimately, health risks can be reduced or avoided entirely. Therefore, breeders should carefully consider their intentions when making breeding decisions.

Economic benefits of selective breeding

Selective breeding has a variety of advantages. It allows you to choose plants and animals with specific traits, which naturally increases the profit of a business. Furthermore, it has zero patent protection. In addition, you can cross-pollinate crops, which can increase profits exponentially. You can also select your pet parents and promote desirable traits in a species. Selective breeding activities don’t require special skills or safety concerns. However, it does require proper knowledge and training.

The economic benefits of selective breeding in aquaculture can include improved productivity, reduced mortality, and more efficient feed conversion. For example, a study showed that by using improved genetics, the cost per fingerling was reduced by 3.1 percent, feed fed per kg of marketed fish decreased by 2.6 percent, and overhead costs decreased by 11.9 percent. The overall benefit of selective breeding in aquaculture is more than $2,000 per year. The increase in profits, which comes from increased survival and weight gain, is the best proof of its positive effects.

Genetic mutations associated with selective breeding

One of the main benefits of selective breeding is that it can enrich homozygous mutations and, in some instances, shift the distribution of liability within a population. For example, mef2ca mutant alleles have been reported in heterozygous people, but they produce dominant phenotypes in the presence of edn1 heterozygosity. However, genetic drift and developmental compensations are other potential side effects of selective breeding.

In the classic experimental study by Robert Tryon, the frequency distributions of genetic variants of a population were plotted over successive generations. The P population was selected for mating pairs that would result in a population with a “Maze-Bright” line and a “Maze-Dull” population with a similar distribution of phenotypes. In addition, animals breeding the P population were not selected based on scores, creating three different reproductively isolated people.
