What is the purpose of finding genetic interactions of a gene? Select one: a. To find its gene clusters on chromosome b. To find if a mutation has happened in that gene c. To find possible pathways a gene might be involved in
Homework Answers
Option B is correct
To find if mutation has happened in that gene.
Genetic interaction is defined as a deviation from the expected natural phenotype i.e., genes responds in an unnatural or different way. It causes changes in genotype and phenotype(sometimes) of the organism.

3) Proto-oncogenes can be converted to oncogenes by various genetic changes. Which of these mechanisms is not likely to contribute to conversion to an oncogene? Select one: A: Extra copies of the gene are made, thereby enhancing expression. B: A mutation occurs upstream of the gene that results in a more active promoter. C: Chromosomes break and fragments are translocated from one chromosome to another. D: Point mutations occur that result in a protein more resistant to degradation. E: All...

A woman has a mutation in a mitochondrial gene that encodes a subunit of the aerobic respiratory Complex IV. What percentage of her male children are expected to harbor this same mitochondrial abnormality? Mitochondrial genetic analysis of the father of these children has revealed that he does not have this genetic mutation. Choose one: O A. 100% of male children will have the mitochondrial genetic mutation. O B. 75% of male children will...

Which of the following is TRUE of incomplete penetrance? Select one: a. Epistatic interactions can result in incomplete penetrance in some cases. b. Environmental factors do not influence penetrance. c. Incomplete penetrance implies that some individuals will experience less severe forms of disease, such as cancer or Alzheimer's. d. Incomplete penetrance is never observed with Huntington's disease e. Incomplete penetrance refers to cases in which individuals developing a particular disease (e.g., cancer or Alzheimer's) lack the typical genotype for this...

3. (35 pts) The gene for the cone photoreceptor in the eye and the gene for a blood-clotting factor are both in the X-chromosome. Suppose they are 14 map units apart. Mutation in the photoreceptor gene results in color blindness, and is inherited as an X-linked recessive trait. Mutation in the clotting factor gene results in hemophilia, and is also inherited as an X-linked recessive trait. You have two patients: Sally and Jill. Both patients have a family history of...
