Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

What is mutation? describe its type and how mutation and evolution are interrelated. Discuss
Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank

What is a gene? Why are regulatory genes important to the evolutionary process? What is a mutation as defined in this course and readings. Are the end results of a mutation always "good" or always "bad"? Or is a mutation perhaps neither always good or always bad and could be "neutral or no effect" or "adaptive" in some situations? Does it depend on the gene, amino acid, protein, and case-by-case scenario? What genetic evidence suggests that humans are a part of a biological continuum with all life forms. Does the number of genes in a biological organism correlate, predict, or denote the complexity of the organism? Does the number of chromosomes in a biological organism correlate, predict, or denote the complexity of the organism?
In the replica plate experiment, it shows that mutations are random. However, certain environmental stresses (such as high temperature, high salt, and low pH) can increase the mutation rate. QUESTIONS: Does increasing the mutation rate increase the probability that an individual mutation will be adaptive?
You are collaborating with a cool new local brewery on an experiment with one of their strains Saccharomyces cerevisiae, brewer’s yeast. You decide to apply what you learned in Evolution to create a mutation accumulation (MA) line to see if the patterns of mutation in their strain of S. cerevisiae follow patterns seen in other species. Which of the following best describes an actual result you observe form studying the mutation accumulation (MA) lines you created? a. Beneficial mutations occur far less frequently than deleterious mutations do. b. The neutral mutations had a greater effect on fitness compared to other mutation types. c. Most of the mutations that occur are the result of large chromosomal rearrangements. d. Of all possible mutation types, deleterious mutations are the most common mutation.
Asthma is a common medical condition that is influenced by genetics and environment. In the US, appraximately 9% of adults have asthma. A recent genome wide association study (GWAS) identifieda genetic variation that increases asthma risk by S0% when a single copy of the risk variant is present in a genome. Which value below would represent the approximate asthma risk of an individual with this genetic variation in their genome? Select an answer and submit.
