1. Mice and Genetics Research: Imagine you are working in a genetics lab with the house mouse Mus musculus, a model organism for genetics research. You want to determine whether a trait you have discovered in mice is dominant or recessive. Explain how you would design an experiment to answer this question. Predict what types of outcomes are possible. Which would indicate that the trait is dominant? Which would indicate that it is recessive? 2. Model Genetic Organisms: Why are mice considered a model genetic organism? Would humans fit this description

To analyze: According to the given information, wild-type allele of a gene has an A-T base pair at a particular location in its sequence, and a mutant allele of the same gene has a G-C base pair at the same location. Apart from this change, the sequences of the two alleles are same. Based on above information, a question is asked as whether this information tells us anything about the dominance relationship of the allele. If yes, we need to explain why. If no, we need to explain why not.
. Imagine you purchased an albino mouse (genotypecc) in a pet store. The c allele is epistatic to other coatcolor genes. How would you go about determiningthe genotype of this mouse at the brown locus? (Inpigmented mice, BB and Bb are black, bb is brown.)
If you continue with biological studies in the future, you are most likely going to carry out fruit fly experiments. Drosophila melanogaster are used in genetics labs due to how inexpensive they are, how visible their traits are, and their high reproductive rate. In Drosophila, the gene for red and white eye colour is found on the X chromosome. The allele for red eyes (XR) is dominant to the allele for white eyes (Xr). You are asked to cross a pure breeding white-eyed female with a pure breeding red-eyed male. What are the genotypes of the individuals involved in this cross? XRXR XRXr XRX- XrXr XRY XrY Genotype of the parent male Answer Genotype of the parent female Answer Genotype of the male offspring Answer Genotype of the female offspring Answer

1. Develop a micro-theme to include the following concepts: a. Differentiate between genetics and heredity b. Compare dominant and recessive traits c. Compare pure and hybrid offspring
in a summary use your understanding of molecular biology to explain that recessive alleles are expressed through transcription and translation, and that they may have functional gene products. Describe how the interaction of the products produced by each allele results in what we see as dominant or recessive traits.
Genetic engineering: If you have the science to back you up, and you can actually "produce" offspring with traits of your liking, would you do it? If you have to limit this, what should these limitations be?
Recessive epistasis: In a cross between fruit flies that are both double heterozygous for modifier gene and coat color, in the total offspring of 192, how many fruit flies have gray- coat, white coat, and black coat? A recessive allele blocks the expression of the coat color of fruit flies. Show your answer and solution.
1. In Drosophila melanogaster (fruit fly) experiment, if we are going to cross male and female red-eyed fruit flies, we have the resulting offspring ratio of 50% red-eyed for female, 25 % for red-eyed male and 25% for white-eyed male. Females which are either homozygous or heterozygous for a trait still expressed eye redness whereas males can easily be affected. Why is this so? a. Females are the carriers of a gene for eye redness b. Y chromosome is responsible for red eyes in fruit flies, c. The gene for eye redness is an X-link dominant trait, d. Having a red-eyed trait is dominantly expressed by females
