Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
Artificial selection or selective breeding is a process of selecting the “advantageous” characteristics from the plants or animals by humans and using them for breeding. There are many advantages of artificial selection:
• More agricultural products, gaining higher profit (for example more milk from cow, or more fruit)
• Elimination of diseases by identifying the plants/animals with disease
• Production of superior breed.
On the other hand, negative effects might also occur, so the disadvantages of artificial selection are:
• Genetic mutations
• Loss of genes
• Diseases
All of these negative impacts are connected and often arise from the breeding of desirable organisms.
