Benefits Of Artificial Selection

1) Artificial selection is the on purposed reproduction of organisms with the objective to achieve favorable traits in the next generation in the population. For instance, humans started to domesticate gray wolves, and they choose to breed individuals with specific characteristics leading to the existence of different dogs with a wide range of phenotypes. In contrast natural selection will favor organisms that have traits that help them to survive in a situation. For example, in the case of birds that have large beaks, they have more possibilities to survives in areas when the seeds present are only big than the small beaks birds which perish.

2) Stabilizing selection is observed when there is a high survival and reproduction of individuals with intermediate phenotypes rather than extreme phenotypes .For example, the birds have

Sexual reproduction leaves half as many copies of genes as asexual reproduction by a female. Also, the cost of meiosis is a fifty percent reduction via asexual reproduction versus sexual reproduction in the number of genes. that parents pass from one generation to the other one. Sexual reproduction provides many benefits such as removing dangerous mutation and crating variation of their genes. That favors offspring in an environmental change. The organisms that only use asexual reproduction doesn’t have purging mutations, it will have a slow accumulation of prejudicial mutations. This organism will have poor survival and reproduction that will lead them to disappear. In addition, a greater genetic variation of offspring produced is an important benefit for sexual reproduction. Asexual reproduction will be used to produce clonal offspring that are well suited if the environment doesn’t change across time and space. Sexual reproduction also provide when some organisms experience variation of pathogens, evolutionary
