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.
Microorganisms that are capable of causing disease are called pathogens. Although microorganisms that cause disease often receive the most attention, it is important to note that most microorganisms do not cause disease. In fact, many probably provide some protection against harmful microorganisms because they effectively compete with the harmful organisms for resources, preventing them from growing.
Answer:
Human sex cells are produced by a two-part cell division process called meiosis.
Explanation:
Through a sequence of steps, the replicated genetic material in a parent cell is distributed among four daughter cells. Meiosis produces gametes with one-half the number of chromosomes as the parent cell
Answer:
The organic evolution are basically different from all the other form of the evolution as, the concept of organic evolution explain the origin of the life. It is the events which basically involve in evolutionary development of many species.
It also specifically involve in the modification of various existing species in the nature not only focus on the new development.
According to the theory of the organic evolution, the world are not created it is evolved with the branch of the life science.
