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
1a. Discuss the role of Gene Flow in evolution 1b. Explain how Natural Selection operates to bring about evolutionary change 1c. Explain the attributes of the Biological Species that ensure that different species do not interbreed. Your essay including references must not exceed 3 pages
One of the key ingredients of evolution by natural selection is variation. Within a population, evolution by natural selection will occur if there is a selective advantage of one variation over another. What are the sources of variation in living populations? Select all that apply. a random mutations to DNA when DNA replicates in reproductive cells b environmental factors that may mutate DNA in gametes c mutations in somatic cells d crossing over during meiosis
You are investigating a newly emerging bacteriophage infecting your bacteria. There is a population of bacteria that are resistant to the disease. The allele frequency of the resistant allele is q=0.43. The mutation rate (Aàa) of the locus is 3.2 x 10-2. Assuming no back mutations, how do you expect the allele frequency of the recessive allele to change in the next generation? a. It will decrease a little b. It will not change c. It will decrease a lot d. It will increase a little e. It will increase a lot
Revise the passage Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.
Most of the genetic information we will get from our genome will not be hard evidence that we will or we won’t get a disease but is rather only probabilistic evidence. a. What does this mean? b. Why might knowing a single gene not tell you if you will get a particular condition?

To understand this research, you must be familiar with some basic genetic terminology. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. dominant allele phenotype The possession of two different alleles of a particular gene is referred to as Reset Help A variation in a DNA sequence at one particular position is called a heterozygosity genotype recessive allele homozygosity single nucleotide polymorphism The appearance of the organism, its observable traits, are referred to as the A variant of a gene for which an individual must be homozygous in order for it to influence the appearance of the organism is a The set of alleles an organism has for a particular trait is the organism's Submit Request Answer
Part 1: Define natural selection. In your definition, be sure to explain whether selection acts on traits or genotypes, and what genomic patterns indicate selection has taken place at a locus. Part 2: Generally, would you expect selection to increase or decrease polygenicity of a trait? Explain why.
In your own words, explain the factors that lead to the Phenotypic variation and its importance to evolution.
