An organism is described as Rr, with red coloring. Rr is the organism’s________ , while red color is its___________. This organism would be___________ (homozygous/heterozygous) for this color gene.
Which of the following statements accurately describes genetic mutations? *
Mutations are a natural process that increases genetic diversity.
Mutations are an unnatural process that always affect the phenotype.
Mutations are an unnatural process that are always harmful.
Mutations are a natural process that only effects genotype, not phenotype.
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 _________.

- Which of the following BEST describes the relationship between genotype, phenotype, traits, and the environment? O Organisms acquire traits during their lifetime that alter their phenotype. This allows individuals to better adapt to their surroundings, and to pass on their phenotypes to their offspring regardless of their genes. An organism's phenotype is largely determined by its genes, or genotype. The relationship between an organism's phenotype and its environment determines the frequency of traits in a population. O The relationship between an organism's environment and its genotype determines the type of phenotype it will develop. Phenotypes are largely determined by the environment and organisms display traits that are unrelated to their genes.arrow_forwardMAKE A simple sketch and label characteristics Choose a human-related organism to study. As you consider strategies to enhance the social value of this organism, think of other desirable attributes that may be added to it. Imagination is a powerful tool, so let it go wild and imagine that you can transfer genes across other animals. For example: A gene from a firefly has been transferred into tobacco plants so that they may glow in the dark, as demonstrated by geneticists. Tobacco pests are less likely to attack at night because of this.arrow_forwardAn individual and a population has certain characteristics.Name these attributes with definitations.arrow_forward

- At the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown. The adaptations which allow survival and reproduction of a certain color of mice in the new environment is due to: variation. lethal mutations. acquired traits. isolation.arrow_forwardIndividuals within the same species have the different DNA "fingerprint," but individuals from different species have same DNA fingerprints.

There are two possible alleles: B, which leads to a black fur, and W, which leads to white fur. Individuals with the genotype BB will have a black fur, individuals with the genotype WW will have white fur, and individuals with the genotype BW will have gray fur. Scientists recorded the fur color of 1,000 mice from the population. They found that 200 mice have black fur, 400 have gray fur, and 400 have white fur. Ten years later, the measurements are repeated. Again, they recorded the fur color of 1,000 mice. They found that 400 have black fur, 400 have gray fur, and 200 have white fur. Part A: Show the Hardy-Weinberg calculations for the beginning and ending populations. Include the values for the equation as well as the p andq values. Show your work.
