Somatic mutations/mosaicism: what does this mean and how can these alter penetrance or expressivity?
Homework Answers
Ans) These are the mutations which are caused by the cells that are non germline. Therefore , it cannot be inherited from parent to their offspring of the cell which is mutated. It occurs during the organism's life and occurs only in few cells due to environmental factors like UV rays.
Penetrance is a property through which people which has specific changes in genes which futher shows sign as well as symptoms of the genetic disorder.
Stay safe and for any query feel free to ask in the comment section.

Changes in protein expression can alter gene function since: High levels of protein mean that the protein can sustain mutations more readily without any harm to the cell. The cell responds only to high levels of protein. Changes in expression can alter regulatory networks. Low levels of protein mean that the protein can sustain mutations more readily without any harm to the cell. The mutations found in the CF gene that result in cystic fibrosis are recessive because: The CF...

How does stress alter the brain? What is the evolutionary purpose for stress and how does the immune system play a role? Can you think of any way to try to develop a new therapy to treat disorders like post-traumatic stress disorder using the information you know from reading this chapter or outside sources? Provide at least 3 references - one can be the textbook. Use proper APA citations. ya i guess people have given referances previously

Genetic QUESTIONS FOR RESEARCH AND DISCUSSION 1. Discuss how incomplete penetrance, variable expressivity, pleiotropy, and genetic heterogeneity can affect the severity of a disease in a family. 2. A person can lower risk of preventable types of cardiovascular disease by exercising regularly and following a diet low in saturated fats and simple carbohydrates and high in fruits and vegetables. Why are these approaches ineffective against long QT syndrome? 3. Explain how the molecular bases of the various forms of long...

1.) Women with mutations in their BRCA1 or BRCA2 genes are more likely to suffer from breast or ovarian cancer at some point in their life than those who are wild-type. However, doctors cannot predict which patients will develop cancer and which patients won’t. Which term best describes the relationship between BRCA1 (or BRCA2) and cancer? Incomplete Penetrance Variable Expressivity Both Neither 2.) Coat color in Labrador retrievers is determined by two alleles at each of two loci Bb and...
