Description
Please answer these 4 questions in great detail
1) Why are mutations necessary to the process of evolution?
2) Albinism is a condition in which the individual lacks melanin pigmentation. Homozygous recessive individuals are affected and make up about one percent of the population. A nonscientist studies the population and claims that albinism can be removed from the population by preventing the mating of all albinos. Will this approach work? Briefly explain
3) Ideas of several eighteenth and nineteenth century scientists had an impact on Darwin and the eventual publication of Origin of Species. Choose two of these individuals and briefly describe how their ideas influenced Darwin.
4) Charles Darwin's thoughts about the nature of life on earth grew from his observations as naturalist aboard H.M.S. Beagle. Write a paragraph describing a sample of what Darwin saw on his five-year voyage.

Question 1
Mutations are significant to evolution since they act as the raw materials to the process.
Mutations facilitate the creation of new alleles and regulatory regions (Biology-pages.info,
2014). However, most of the visible mutations are harmful such as missence mutations while
some are neutral. The neutral mutations include silent mutations that encode amino acid and
mutations in the vast DNA amounts that are found between the genes. Additionally, most
mutations that occur in genes have effects on a set of proteins that are related or single protein,
but much evolution change involves myriad functional or structural phenotype changes. In the
process of evolution, the mutational changes in genes, especially point mutations, lead to
significant changes that bring differences between species.
To begin with, the duplication of genes during mutation converts harmful effects into
neutral ones or tolerable ones (Biology-pages.info, 2014). In the process of conversion, there is a
provision of the second pair of genes during the gene duplication that occurs in diploid
organisms. Subsequently, the parent pair remains intact during a mutation while the other pair
undergoes a safe mutation and safe testing during various combinations. Secondly, not all cel...
