What are the consequences of artificial selection?
This process is immoral as it induces fear and anxiety in whatever animals are being subjected to a new environment. On top of this, artificial selection can have detrimental effects on these animals, such as obesity, diseases, health disorders, and can even lead to smaller brain size.
What are advantages and disadvantages of selective breeding?
One big advantage of selective breeding is its capability to eliminate animal and plant diseases. Studies revealed that identifying and pre-screening particular diseases allows farmers to control them. Thus, sooner or later, genetic diseases in plants and animals in the future will be eliminated.
What are some advantages or benefits of artificial selection?
- Almost free, if one is in the agriculture business.
- Able to produce crops with higher yield, shorter harvest time, higher resistance to pest and diseases and better taste in an inefficient yet somewhat natural way.
- No safety issues such as those brought about by genetic engineering.
What is the advantage and disadvantage of genetic engineering?
Genetic engineering may create stronger, healthier plants and animals. It may also create more plants and animals with mutations or birth defects that can harm the species. We have already seen in humans that gene therapies can lead to additional genetic conditions, even if the targeted condition is improved.
How do environmental factors affect natural selection?
Explanation: In a population, the natural selection will favour the individuals with the higher fitness (In other words : the ones which have the best chances to survive and reproduce) in a given environment. It means that, for different environment, one gene can give different trait values at the phenotypic level.
How do environmental factors and genetic factors affect natural selection?
Genetic variation and environmental factors work together to cause natural selection because natural selection is caused so that an organism can adapt and better survive in their environment. They are involved in the formation of fossils because organisms that die are buried in sediments and become fossils.
How do environmental factors affect evolution?
Environmental change and isolation of groups of organisms play an important role in evolution. Change in an organism’s environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species.
How can changes in the environment affect the survival of the species?
Loss and Degradation of Habitat The degradation, including pollution, of habitat causes animals to have shorter lives in which they are less likely to breed, and their overall population decreases. Both of these changes in environmental conditions make it difficult for species to survive.
How does extinction of animals affect humans?
Scientists have also discovered links between the incidence of West Nile virus and hantavirus and local reductions in biodiversity. Animal extinctions may also rob humans of valuable medical advancements. Many different species have unique bodily processes that can offer insight into curing human disease.
