Answer - Incomplete Penetrance
An allele is described as a complete penetrance if all individuals possess the mutation that leads to disease condition eg- Autosomal dominant disorder.
An incomplete is a reduced penetrance in which some individuals will not express the trait even though they carry the allele.
Example - In breast cancer which is caused by mutations in the BRCA1 gene is Incomplete Penetrance because females with a BRCA 1/2 mutation in this gene will have an 80% risk of developing breast cancer and not 100%. Hence it is Incomplete Penetrance of 80%.

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...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
